A 1.5kg trolley moving along a straight track at 4m/s is brought to rest by a constant force applied opposite to its motion in 2s. The same force continues to act for another 3s.
(a) Calculate the magnitude of the force applied on the trolley.
(b) Determine the speed of the trolley at the end of the fifth second and state its direction with respect to the initial motion.
