a. A rail road flat car of mass M can roll without friction along a straight horizontal track . Initially, a man of mass m is standing on the car which is moving to the right with speed v0. What is the change in velocity of the car if the man runs to the left so that his speed relative to the car is vrel just before he jumps off at the left end? b. If there are n men each of mass m on the car, should they all run and jump off together or should they run and jump one by one in order to give a greater velocity to the car?

You are standing perfectly still and then you take a step forward. Before the step your momentum was zero ,
Two trolleys A and B are free to move on a level frictionless track, and are initially stationary. A man on trolley A throws a bag of mass 10kg with a horizontal velocity of 4ms−1 with respect to himself on to trolley B of mass 100kg. The combined mass of trolley A (excluding bag) and the man is 140km. Find the ratio of velocities of trolleys A and B, just after the bag lands on trolley B.

A shell is fired from a cannon with a speed of 100 m/s at an angle 30∘ with the vertical (y-direction). At the highest point of its trajectory, the shell explodes into two fragments of masses in the ratio 1:2. The lighter fragment moves vertically upwards with an initial speed of 200 m/s. What is the speed of the heavier fragment at the time of explosion?
