End of phase 1 review Where necessary assume ? = 9.8 ??−2 1. Find the total distance travelled by the body from the following velocity time graph: 2. Draw an acceleration time graph for the veloc... ity time graph above. 3. A ferry carries passengers between banks of a river, which are 20m apart. After setting off, the ferry accelerates at 0.2??−2 for 12 seconds before turning off the engine and decelerating at a constant rate and coming to a stop at the opposite bank. a) Calculate the speed of the ferry after the first 12 seconds. b) Calculate the distance the ferry travels during these 12 seconds. c) Calculate the value of the ferry’s deceleration after the engines are turned off. d) State any assumptions you made in part (c) and explain why, in reality, this value would be higher.
