A body of mass m=1kg falls from a height h=20m from the ground level . (a) What is the magnitude of total change in momentum of the body before it strikes the ground? (b) What is the corresponding average force experienced by it ?(g=10ms^(-1))

a car of mass 1500 kg collies with a wall as shown in fig. The initial and final velocites on the car are vec(v_i)=-15.0 hat(i)ms^(-1) and vec(v_f)=5.00 hat(i) ms^(-1) find the impulse caused by the collision and the average force exerted on the car. In a paricular crash test respectively. If the collision lasts 0.150s
