An electric vehicle starts from rest and accelerates at a rate of 2.0 m/s2 in a straight line until it reaches a speed of 22 m/s. The vehicle then slows at a constant rate of 1.2 m/s2 until it stops. (a) How much time elapses from start to stop? (b) How far does the vehicle move from start to stop?
A car starts from rest
at a stop sign. It accelerates at 3.7 m/s^2 for 6.1 s , coasts for
2.4 s , and then slows down at a rate of 3.3 m/s^2 for the next
stop sign.
Question: How far apart are the stop signs? (Express
your answer to two significant figures and include the appropriate
units.)
