A car starts from rest at a stop sign. It accelerates at 3.7 m/s2 for 6.5 s , coasts for 1.9 s , and then slows down at a rate of 2.5 m/s2 for the next stop sign. How far apart are the stop signs?
We use equations of uniformly accelerated motion for the three stages of motion in the problem to get the total distance covered before stopping again.

A car starts from rest at a stop sign. It accelerates at 2.0 m/s2 for 5.6 seconds, coasts for 2.9 s , and then slows down at a rate of 1.5m/s2 for the next stop sign. How far apart are the stop signs?
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.)

A subway train starts from rest at a station and accelerates at a rate of 1.60 m/s2 for 10.0 s. It runs at a constant speed for 50.0 s and slows down at a rate of 3.20 m/s2 until it stops at the next station. How far apart are the two subway stations? A 40 m B 80 m C 800 m D 920 m E None of the above.
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?
An electric vehicle starts from rest and accelerates at a rate of 2.2 m/s2 in a straight line until it reaches a speed of 22 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 until it stops.(a) How much time elapses from start to stop (in seconds)?(b) How far does the vehicle travel from start to stop (in meters)?
An electric vehicle starts from rest and accelerates at a rate of 2 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle then slows at a constant rate of 1 m/s2 until it stops. (a) How much time elapses from start to stop? (b) How far does the vehicle travel from start to stop?
2. A car starts from rest at a stop sign. It accelerates at 2.5 m/32 for until it reaches a speed of 50 km/hr. (1 km/hr .278 m/s) (a) Draw a picture of this problem (not a motion diagram but a picture!) clearly indicate on your picture where you call x-0, t-0 i.e. establish a coordinate ystem. Label it with symbols representing initial positon, initial velocity, final position final time, final velocity and acceleration and include all the information you...
