Wide Balls Problems Fixed

Two identical uniform solid spherical balls A and B of mass m each are placed on a the fixed wedge as shown in figure. Ball B is kept at rest and it is released just before two balls collides. Ball A rolls down without slipping on inclined plane and collide elastically with ball B . The kinetic energy of ball A just after the collision with ball B is:

Two small identical balls lying on a horizontal plane are connected by a weightless spring. One ball (ball 2) is fixed at O, and the other (ball 1) is free. The balls are charged identically as a result of which the spring length increases eta=2 times. Determine the change in frequency.

A ball is wbhirled ina circle by attaching it to a fixed point with a string. Is the an angular rotatioin of the ball about its centre? If yes, is this angular velocity equal to the angular velocity of the ball about the fixed point.

In the previous problem , time taken by the ball up to the third collision

Mahesh has certain number of problems with him. He can solve some fixed number of problems every hour. After solving for 5 hours, he is left with 384 problems. If he had solved for 10 hours, he is left with 144 problems to solve. Find the number of problems with Mahesh initially.

In the previous problem if the car is moving with a constant acceleration of 2 m//s^(2) , the ball will fall behind the person at a distance
