We start by noting that all the motion given is moving to the right or in the positive direction. The driver then applies the brakes causing a uniform negative acceleration of -30 ms2. Graph the scooters velocity versus time.

Unless otherwise noted use g 1 0 m s 2 and neglect air resistance A. A car with a velocity of 30 ms accelerates uniformly at the rate of 20 ms2 for 10 s. So in part C plugging in the numbers we get 115 meters as the position and the speed is 3 meters per second.

You can convert units to kmh by multiplying the result by 36. Explain how you could use the graph to show that the scooters acceleration is constant during the intervals 10-20 s and 50-60 s. And then for Part D we have all the quantities for part D here.
