Classes are canceled due to snow, so you take advantage of the extra time to conduct some physics experiments. you fasten a large toy rocket to the back of a sled and take the modified sled to a large, flat, snowy field. you ignite the rocket and observe that the sled accelerates from rest in the forward direction at a rate of 13.513.5 m/s2 for a time period of 3.503.50 s. after this time period, the rocket engine abruptly shuts off, and the sled subsequently undergoes a constant backward acceleration due to friction of 5.155.15 m/s2. after the rocket turns off, how much time does it take for the sled to come to a stop?
by the time the sled finally comes to a rest, how far has it traveled from its starting point?
