A car is moving along a straight horizontal road. At time t=0t = 0t=0, the car passes a point A A\,A with speed 25 m s-1. The car moves with constant speed 25 m s-1 until t=10 st = 10 \text{ s}t=10 s. The car then decelerates uniformly for 8 s. At time t=18 st = 18 \text{ s}t=18 s, the speed of the car is V m s−1V \text{ m s}^{-1}V m s−1 and this speed is maintained until the car reaches the point B B\,B at time t=30 st = 30 \text{ s}t=30 s.
Sketch a speed–time graph to show the motion of the car from A A\,A to BBB.
Given that AB=526 mAB = 526 \text{ m}AB=526 m, find the value of VVV.
Find the deceleration of the car between t=10 st = 10 \text{ s}t=10 s and t=18 st = 18 \text{ s}t=18 s.
