Question

A ball moving on a horizontal frictionless plane hits on indentical ball at rest with a velocity of 50 m/ sec If the collisions in elastic , calculate the speed imparted to the Target ball if speed of the striking ball after the collision is ​

Answer 1

Answer:

At first the velocity of the ball is 50m/sec.

After striking the elastic the force of the elastic is converted to the ball.

so the final velocity of the is being multiplied by 2 times.

The velocity of the ball is 100m/sec.

Answer 2

Answer:

velocity of second ball is 50m/s

Explanation:

The balls are identical and in collision the momentum is conserved so,

The first ball comes to rest after the collision and the momentum of the first ball is transfered to second ball so it gets 50m/s velocity
