A girl of mass 40kg jumps with a horizontal velocity of 5m//s onto a stationary cart with frictionless wheels. The mass of the cart is 3kg . What is her velocity as the cart starts moving? Assume that there is no external unbalanced force working in the horizontal direction.

When the growth of GDP in a country slows down suddenly people start losing their jobs and the situation continues for several weeks, what name is given to this state of economy ?

Two persons are applying forces on two opposite sides of a moving cart. The cart still moves with the same speed in the same direction. What do you infer about the magnitudes and direction of the forces applied.

A man (mass = 50 kg) and his son (mass = 20 kg) are standing on a frictionless surface facing each other. The man pushes his son so that he starts moving at a speed of 0.70 m s^(-1) with respect to the man. The speed of the man with respect to the surface is:
