Momentum = (mass) x (speed) = 7,500 poundmass-miles per hourAfter laboriously converting all of that to metric units for you ... at noextra cost ... we find that the momentum is equivalent to1,520.8 kilogram-meters/second
16 meters squared
First, we have to do some mental gymnastics and decide what the question means by "different but identical".Let's assume it's talking about two copies of the same item, like two separate identical twins.What the question seems to be describing is the situation where both balls are rolling horizontallyacross the table toward the edge. One is rolling much faster than the other, but they both reach theedge and fall off at the same instant.They will hit the floor at the same instant. The one that was rolling faster before the fall will hit thefloor farther from the foot of the table, but the two "clunks" as they hit will come at the same instant.
8.5 meters or 8 1/2 meters
The width of the rectangle is 13 meters. The perimeter of the rectangle is 50 meters, and its length is 12 meters. The 50 meters is 2 times the length plus 2 times the width. With a length of 12 meters, twice that is 24 meters. That leaves 50 meters - 24 meters for twice the width. And 50 - 24 = 26, which is twice the width. The 26 meters divided by 2 = 13 meters, which is the width of the rectangle.
The kinetic energy of the ball can be calculated using the formula: KE = 0.5 * mass * velocity^2. Plugging in the values for the mass (3 kg) and velocity (2 m/s), the kinetic energy of the ball would be 6 Joules.
40 Joules
Joules are the SI unit for energy. One Joule is equal to one kilogram meters squared per seconds squared (kgm2/s2).
Momentum does not have the same units as the others. Kinetic energy is measured in joules, potential energy in joules, work in joules, but momentum is measured in kilogram meters per second (kg m/s).

To find the kinetic energy of the object at 2 meters height, we need to consider the conservation of energy. At a height of 2 meters, the object will have potential energy of mgh = 5kg × 9.81m/s^2 × 2m = 98.1 Joules. Since no external work is being done on the object, this potential energy will be converted into kinetic energy. Thus, the kinetic energy of the object at 2 meters height will be 98.1 Joules.
No, a joule is the unit of energy, equivalent to one watt-second. It represents the amount of energy transferred or converted within a system. On the other hand, meters per second per kg is the unit of specific kinetic energy, representing the kinetic energy per unit mass of an object moving at a certain velocity.
KE = 1/2 m V2 = (12) (2)2 = 48 joules
Kinetic Energy = 1/2(mass in kilograms)(meters per second)2
The kinetic energy of the student can be calculated using the formula KE = 0.5 * mass * velocity^2. Plugging in the values, we get KE = 0.5 * 60 kg * (3 m/s)^2 = 270 Joules.
Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.
Kinetic energy = 1/2 x mass x velocity2. Mass in Kg, velocity in meters/sec, energy in Joules
