It travels with constant acceleration for 4 seconds reaching a velocity of 5 m/s. It then slows down with constant deceleration of 1 m/s2 for 2 seconds. It then hits a wall and stops. Draw a velocity-time graph for the toy car. Work out the total distance travelled by the toy car.
At what time will the second train reach the first? We will be using the formula d = vt extensively in these problems. Let’s build a chart. The goal is to have TWO, not three or more, variables present in the chart.
