Question

if i throw a ball straight up, wait for it to come down and then catch it, how does the final velocity of the ball compare to the inital velocity of the ball

Answer 1

The final velocity of the ball when you catch it is equal in magnitude but opposite in direction to the initial velocity with which you threw the ball upward.

Step-by-step explanation:

The final velocity of the ball when you catch it will be equal in magnitude but opposite in direction to the initial velocity with which you threw the ball upward. This is because the ball undergoes free fall when it is coming back down, and in the absence of air resistance, the vertical motion of a falling object is solely influenced by gravity. Therefore, the final velocity will have the same magnitude as the initial velocity, but with a negative sign to represent the opposite direction.
