A toy car accelerated from rest for 2.8 seconds, then continued at its maximum speed of 1.8 m s-1 until 8.2 seconds, then put on its brakes and decelerated to a stop in 12.5 seconds. Its motion is plotted on the graph below. How far did it travel when it accelerated (\( t_1 \))? Give your answer to two decimal places.

Step-by-Step Analysis
First, restate the given data from the problem to anchor the calculation: the toy car accelerates from rest for t1 = 2.8 s to reach a maximum speed of 1.8 m/s, then continues at that speed until t = 8.2 s, and finally brakes to a stop in 12.5 s. The question asks for the distance traveled dur......Login to view full explanationLog in for full answers
