QUESTION 6   A bоy pushes his little brоther in а cаrt. The cаrt starts tо move.    Right click on the button to open the picture of the boy and his brother in a new window.   The little brother and cart have a total mass of 50 kg. They travel at a velocity of 4 m/s.    6.1 State the relationship between momentum, mass and velocity.  (1) 6.2 Calculate the momentum of the little brother and cart.  (3) 6.3 The boy applies a steady force for a time of 1.5 s. The momentum of the little brother and cart increases by 450 kg m/s. Calculate the force which the boy applies.  (3) 6.4 Momentum is a vector quantity. State what is meant by a vector quantity.
