1(a) A 4 kg object is travelling at u = 3 m/s when a constant unbalanced (net) force of magnitude 10 N is applied in the opposite direction of its motion. Apply the Work-Energy Theorem to find the displacements of the object at the moments at which its velocity becomes (i) u/2 and (ii) zero, respectively. (b) A 4 kg object is travelling at u = 3 m/s when a constant unbalanced (net) force of magnitude 10 N is applied in the opposite direction of its motion.
