Without knowing initial velocity ? Hmmm. That could make it difficult.
Our best advice would be to use what you do know to find what you're looking for.
You cant.
It's 63.7 meters/second faster than its initial speed, downward, and 63.7 meters/second slower than its final speed, downward. Without knowing either of those, we can't calculate the specific number.
You use the information that you do have, along with the formulas, equations, anddefinitions you've learned that express the relationship among quantities such asposition, speed, velocity, acceleration, and time, to find the unknown quantity.
Such and object is said to be in equilibrium. No acceleration and no force.
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
Speed is a scaler quantity i.e. it has magnitude only without direction. It can be calculated using the formula : speed = distance/time where distance is the total distance travelled from initial position to final position; time is the total time taken to cover this distance. Velocity is a vector quantity i.e. it has magnitude as well as direction. It can be calculated using the formula : velocity = displacement/time displacement is the distance between final position & initial position; time is the total time taken to cover this displacement. for example: if a body starts from some initial point goes to a certain distance x and returns back to the initial position. So the total distance covered is 2x but displacement is 0 (zero) because initial & final position are same. So its speed is 2x/time while velocity is 0/t = 0(zero)
You cant.
You can not make a decisive answer without knowing the MASS of the Object and its relative POSITION and Velocity in its Reference Frame. They could be Equal, or either one greater than the other.
There is no answer to your question without knowing the direction of the velocity and of the force application.
Define a moving coordinate system with respect to a stationary object.
Without knowing the position it's difficult to identify the skills needed.
No way to answer without knowing the weight of the weapon, weight of the projectile, velocity of the projectile
Because of its velocity (velocity is the rate of change of position), an object will move. An object is stationary if it has no velocity because it will not be able to move without velocity. Therefore, you can tell that an object has moved because of velocity.
Without knowing why they have adopted that position you do not try to change it. To assume there is a 'cure' is ignorance. Do not try.
Well, we know that velocity describes the speed and direction of motion, so you can't change either of those. We don't usually think of 'position' as a characteristic of motion, but if we try hard to please you, then we might observe that the position changes while velocity remains constant.
Impossible to say without knowing the initial value.
