Two identical buggies of each of mass `150 kg` move one after the other friction with same velocity `4m/s`. A man of mass `m` rides the rear buggy. At a certain moment, the man jumps into the front buggy with a velocity v relative to his buggy. As a result of this process, real boggy stops. If the sum of kinetic energies of the man and the front buggy just after collision with the from buggy differs from that just before collision by `2700 J` then
the mass `m` of the man is

Two identical buggies of each of mass 150 kg move one after the other friction with same velocity 4m//s . A man of mass m rides the rear buggy.

If the sum of kinetic energies of the man and the front buggy just after collision with the from buggy differs from that just before collision by 2700 J then The velocity v of the man relartive to the buggy is

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.

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?

A man is standing on a cart of mass double the mass of man. Initially cart is at rest. Now, man jumps horiozontally with velocity u relative to cart. Then work done by man during the process of jumping will be

A wagon of 200 kg is moving on a smooth track with velocity of 2 m//sec . A man of 80 kg also runs in the wagon with a velocity such that speed of the centre of mass of the system is zero. Find the velocity of man relative to the wagon (in m//s).

A baloon of mass M is stationary in air. It has a ladder on which a man of mass m is standing. If the man starts climbing up the ladder with a velocity v relative to ladder, the velocity of balloon is
