of its acceleration?
b. What net force is needed to provide this acceleration?
c. How far will the bike travel in the 2.0 s?

Answer:

See below

Explanation:

acceleration = change in velocity / change in time

                     =   - 10 m/ s  /  2 sec =  -  5 m /s^2    = 5 m/s^2 (magnitude)

F = ma    =   25 kg * 5 m/s^2 = 125 N

x = vo t + 1/2 at ^2

  = 10 (2)  + 1/2 ( -5)(2^2 ) = 10 meters
