Question

A boy of mass 50kg jumps with horizontal velocity of 5m/s onto a stationary cart with frictionless
wheels. The mass of the cart is 4 kg. What is his velocity as the cart starts moving? Assume that
there is no external unbalanced force working in horizontal direction

Answer 1

Answer:

m1u1 + m2u2= m1v1 + m2v2

50×5 + 4×0. = (50+4)v

250 + 0. = 54v

v= 250/54

v = 250/54 = ?
