Two men, each of mass m, stand on the edge of a stationary buggy of mass M. Assuming the friction to be negligible, find the velocity of the buggy after both men jump off with the same horizontal velocity u relative to the buggy: (1) simultaneously, (2) one after the other. In what case will the velocity of the buggy be greater and how many times?

A buggy of mass 100 kg is free to move on a frictionless horizontal track. Two men, each of mass 50 kg, are standing on the buggy, which is initially stationary. The men jump off the buggy with velocity =10m/s relative to the buggy. In one situation, the men jump one after the other. in another situation, the men jump simultaneously. what is the ratio of the velocities of the buggy in two cases?

Two boys each of mass 40 kg are standing on the right side of a trolley of mass 80 kg , initially at rest on smooth floor. The boys jumps to the right with velocity 3 m//s with respect to the trolley before the jump. Find the final velocity of the trolley if the jumps : (a) together , (b) one after the other and (c ) one boy is on the left and the other on the right , the boy on the left jumps to the left and then the boy on the right jumps to the right. Each boy jumps with 3 m//s with respect to the trolley before the jump.

A mass m moving with a speed u collides on a similar stationary mass and sticks to it. What is the velocity after collision?

A body of mass 10 kg and velocity 10 m/s collides with a stationary body of mass 5 kg . After collision both bodies stick to each other , velocity of the bodies after collision will be

A man of mass m is standing on a stationary flat car of mass M. The car can move without friction along horizontal rails. The man starts walking with velocity v relative to the car. Work done by him

A boy of mass m is riding on a trolley of mass M which is moving on smooth floor at speed v_(0) . He jumps off in the opposite direction of motion of trolley with velocity u relative to the trolley before the jump. Find the velocity of the trolley after jump.

A body of mass m moving with a velocity strikes a stationary body having same mass . What will be the ratio of velocity of two bodies after the collision if the coefficient of restitution is e .

Two identical buggies move one after the other due to inertia (without friction) with the same velocity v_0 . A man of mass m rides the rear buggy. At a certain moment the man jumps into the front buggy with a velocity u relative to his buggy. Knowing that the mass of each buggy is equal to M, find the velocities with which the buggies will move after that.
