Define acceleration. shows the speed-time axes for the graph of the motion of a car. time / s speed m / s The car starts from rest. From time = 0 to time = 15 s, the car has a constant acceleration to a speed of 28 m / s. From time = 15 s to time = 32 s, the car has a constant speed of 28 m / s. From time = 32 s, the car has a constant deceleration of 2.0 m / s2 until it comes to rest. On , draw the graph, using the space below for any calculations. From time = 15 s to time = 32 s, the path of the car is part of a circle. For this motion, state 1. the direction of the resultant force on the car, 2. what happens to the velocity of the car.

shows students getting onto a school bus. A student describes part of the journey. The bus accelerates from rest at a constant rate for 10 s. It reaches a maximum speed of 10 m / s. The bus maintains a constant speed of 10 m / s for 60 s. The bus then decelerates at a constant rate for 15 s, until it stops. On , draw the speed-time graph for this part of the journey made by the bus. time / s speed m / s On another part of the journey, the average speed of the bus is 7.5 m / s. Calculate the distance the bus travels in 150 s. distance = m
