When an object with a momentum of 80 kg by meters per second collides with an object with a momentum of negative 100 kg times meters per second the total momentum after the collision is?
We have to assume that both bodies are initially moving along the same straight line in opposite directions, so the collision is "head on". We also have to assume that the collision is "elastic", meaning that none of the original kinetic energy is lost to heat. The final momentum is 20 Kg-m/s in the direction opposite to the original 80 kg-m/s motion.
What has greater mass 1mL or 4mL?
our bodies are mainly composed of liquid (water), which is measured in ml's, so 4ml's has greater mass eventhough is not solid, it's still part of the weight added to anything solid or space.
A pyramid is a what?
Dead Bodies. The pyramids protected the dead bodies.
What organisms have segments bodies?
Organisms with segmented bodies include annelids, such as earthworms and leeches, as well as arthropods like insects, spiders, and crustaceans. These segments often serve specific functions and allow for greater flexibility and mobility. In some chordates, such as vertebrates, segmentation is also evident in structures like the vertebral column. This segmentation is a key feature that contributes to the complexity and adaptability of these organisms.
Why does a warm ball bounce higher than a cold ball?
When any thing is heated its volume is increased and as a result of the same its weight is decreased. Weight of a body is the force through which earth pulls it towards it (earth).When a body is bounced its weight resists the bounce. Greater the weight greater will be resistance. Heated bodies due to reduction in weight provide lesser resistance in its bouncing.
Why heavier body needs greater initial effort to put them in motion?
Heavier body have grater mass which leads to greater force requirement to put them in motion. Force is given by F=ma Therefore, if m is greater than required force F is greater. Secondly, the inertia of rest of heavier object is greater than the lighter object hence the greater initial effort is required
Why is the law of conservation of momentum useful in analyzing the collision between two bodies?
The law of conservation of momentum useful in analyzing the collision between two bodies because there is use to be the collision between the two bodies reason for that is law of conservation of momentum is that the total sum of momentum is equal means constant after the total sum of momentum of two bodies. so if you don't be the collision between two bodies you will not aware of the meaning of momentum.
Which body moves faster heavier or lighter?
In a vacuum, all objects fall at the same rate regardless of their weight due to gravity. However, in real-world conditions with air resistance, lighter objects tend to fall slower than heavier objects because air resistance affects lighter objects more.
Damage is more when two bodies collide from opposite directions than when they collide at any other angle.Is it due to the momentum of the objects or their relative velocities?
The increased damage when two bodies collide head-on is due to the momentum of the objects, which is the product of their mass and velocity. When two bodies collide from opposite directions, their momentums add up, resulting in a greater force of impact compared to collisions at other angles where momentums may partially cancel out.
Why are heavier people stronger than lighter individuals?
Heavier people are often stronger than lighter individuals because their bodies have more muscle mass and can generate more force to lift or move objects. Additionally, carrying extra weight can also lead to increased muscle development and strength over time.
Equal forces F act on isolated bodies A and B The mass of B is three times that of A The magnitude of the acceleration of A is?
Three times greater than the magnitude of the acceleration of B. This is because acceleration is inversely proportional to mass when the force acting on the bodies is kept constant. Given that the force acting on both bodies is the same, the lighter body (A) will experience a greater acceleration compared to the heavier body (B).
Why one or both ends of some of the blackworms are lighter in color than the rest of their bodies?
Why one or both ends of some of the blackworms are lighter in color than the rest of their bodies
What do tigers have to make them stronger then lions?
Heavier, more muscular bodies.
How is momentum conserved after two object collide?
From Newton's third law, when two bodies A and B collide, the force that A exerts on B is equal in magnitude but opposite in direction to the force that B exerts on A. From Newton's second law, this force produces a rate of change of momentum. Both bodies are experienced to the same magnitude in change of momentum but in opposite directions. Net change in momentum is zero. This implies that momentum is conserved.
When two bodies having same momentum collide what will be the result?
There are two possible results. However, they cannot move in the same direction after the collision.Total initial momentum = p - p = 0where p represent the momentum of each object.From the principle of conservation of momentum;Total initial momentum = Total final momentumThus, Total final momentum = 0There are only two possibilities for this:1. Kinetic energy is conserved. (the collision is perfectly elastic)In this case, they would move away from each other with the same magnitude of initial momentum.2. Kinetic energy is not conserved. (the collision is inelastic)In this case, they would either remain at rest or they will move away from each other with a smaller magnitude of initial momentum each had.Note that if both bodies had moved in the same direction, there would be a net momentum in this direction and momentum would not have been conserved. (Momentum is ALWAYS conserved provided there is no external force acting on the system)
What is the relationship between momentum and law of conservation of momentum?
The law of conservation of momentum states that the total momentum of a closed system remains constant if no external forces are acting on it. Momentum itself is the product of an object's mass and velocity. Therefore, the relationship between momentum and the law of conservation of momentum is that the total momentum of a system before a collision or interaction must be equal to the total momentum after the collision or interaction.
When you die do you get heavier or lighter?
Dead bodies begin to lose water almost immediately. Although some weight is gained by oxidation, more is lost to evaporation and gaseous deterioration. The calcified bones remain, but without the marrow and fluids they are only half of their "living" weight.
