Theoretically, if the objects have the same mass and are moving towards each other at a speed of 
, after a perfectly elastic collision, the object A is supposed to move with the same velocity in the opposite direction.

Answer:
Angular acceleration of the disk will be
Explanation:
We have given mass of the disk m = 5 kg
Diameter of the disk d = 30 cm = 0.3 m
So radius
Moment of inertia of disk is given by
Force is given by F=4 N
Torque is given as
We also know that torque is given by
Explanation:
Given that,
Mass of the rock climber, m = 90 kg
Original length of the rock, L = 16 m
Diameter of the rope, d = 7.8 mm
Stretched length of the rope,
(a) The change in length per unit original length is called strain. So,
(b) The force acting per unit area is called stress.
(c) The ratio of stress to the strain is called Young's modulus. So,
Hence, this is the required solution.
