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 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?
A car starts from rest at a stop sign. It accelerates at 4.6 m/s2 for 7.4 s , coasts for 1.5 s , and then slows down at a rate of 3.2 m/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 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 4.0 m/s2 for 9 seconds, coasts for 4 s, and then slows down at a rate of 3.0 m/s2 for the next stop sign. Howfar apart are the stop signs?

a car starts from rest at a stop sign. It accelerates at 4.4m/s² for 7.5s, coasts for 1.9s, and then slows down at a rate of 2.8m/s² for the next stop sign.how far apart the stop signs?
A drag racer starts her car from rest and accelerates at 10.4 m/s for a distance of 395 m. (a) How long did it take the race car to travel this distance? 7.5 x Your response differs from the correct answer by more than 10%. Double check you (b) What is the speed of the race car at the end of the run? (No Response) m/s
Prob. 2 A car starts from rest, accelerates at 1.5 m/s, and reaches a maximum speed vi. After that it decelerates at 2 m/s until it stops. During the entire process the car has traveled a distance of I km. (a) Sketch the velocity diagram of the particle during the process. (Leave vI as an unknown on the diagram) (b) Determine the maximum speed vi. (e) Determine the total time required.
1 (a) A car accelerates from rest to a speed of 10.9 m/s in 8.4 seconds. Find the magnitude of the average acceleration. (b) If I accelerate for 5.3 seconds in my car at 2.6 m/s2 when I have an initial velocity of 20.9 m/s, what final velocity do I have? (c) If I apply an acceleration in the opposite direction to my initial velocity for 7.4 seconds of -3.2 m/s2 when I have an initial velocity of +21.6 m/s,...
