Previous Question: A ball falls vertically downward and bounces off a horizontal floor. The speed of the ball just before reaching the floor (u1) is equal to the speed just after having contact with the floor (u2); u1 = u2 . The corresponding magnitudes of accelerations are denoted respectively by a1 and a2 . The air resistance during motion is proportional to speed and is not negligible. If g is acceleration due to gravity, then option (A) a1 < a2 (B) a1 > a2 (C) a1 = a2 g (D) a1 = a2 = g Next Question: A boat crossing a river moves with a velocity v relative to still water. The river is flowing with a velocity v/2 with respect to the bank. The angle with respect to the flow direction with which the boat should move to minimize the drift is option (A) 30 degree (B) 60 degree (C) 150 degree (D) 120 degree
