Question

a heavy steel ball is stucked by a small stael pallet moving horizontal with 20m/sec if pallet bounc of steel ball withvno sleeping and rises vertically to height 10 meter above the point of contact what is 100 times elastic cofficient of restitution is 100e​

Answer 1

Explanation:

Two steel balls fall freely on an elastic slab. The first ball is dropped from a heightand the second from a heightafter the first ball. After the passage of time T, the velocities of the balls coincide in magnitude and direction. Determine the time T and the time interval during which the velocities of the two balls will be equal assuming that the balls do not collide

Answer 2

Answer:

The answer is 50 $\text{m~s}^{-1}$

Explanation:

Since the steel ball is heavy, assume it to be fixed.

The momentum of the pallet along any line in the tangent plane to the sphere at the point of contact will remain the same.
