Question

two balls A and B of same masses are thrown from the top of the building A, thrown upward with velocity V and B , thrown downward with velocity V, then
(a) velocity of A is more than B at the ground
(b) velocity of B is more than A at the ground
(c)Both A and B strike the ground with same velocity
(d)none of the above
​

Answer 1

Answer:

Both strike the ground with same velocity.

Explanation:

let the velocity of a(thrown up) be v, when it comes back to the height of the building, it's velocity will be v in the downward direction (which is the same way B was thrown), so they both will hit the ground with same velocity but at different times.

Answer 2

c) Both a and b will strike the ground with same velocity
