2 Section A Answer all questions in this section. 1 Fig. 1.1 shows a man cycling forward on a straight road surface P. After cycling for 10 s, he enters a road surface Q. Throughout the entire journey, the man exerts a constant forward driving force of 600 N. Fig. 1.1 Fig. 1.2 shows a graph of the resistive force acting on the bicycle against time. Fig. 1.2 The man and his bicycle have a combined mass of 150 kg. His initial speed is 2.0 m/s . (a) Calculate the acceleration of the man and his bicycle at t = 5 s. acceleration = …………………….………………….[2] (b) Calculate the speed of the bicycle at t = 10 s. speed = ………………………………...……..[2]

3 (c) Describe the velocity and acceleration of the cyclist from 10 s to 20 s. …………………………………………………………………………………………………….. …………………………………………………………………………………………………….. ………………………………………………………………………………………………….[1] 2 Fig. 2.1 shows an archer shooting an arrow at a target during a competition. Fig. 2.1 (a) The arrow has a mass of 0.025 kg and is initially at rest. The arrow leaves the bow 0.013 s after the bow string is released. When it leaves the bow, the velocity of the arrow is 86 m/s.
