Acar is traveling at 26.0 m/s when the driver suddenly applies the brakes, causing the car to slow down with constant acceleration. the car comes to a stop in a distance of 120 m.
1st find acceleration -> then use it to solve.
how fast was the car moving when it was 60.0 m past the point where the brakes were applied?

a = -2.82 m/s²

v = 18.4 m/s

Explanation:

Initial velocity, u = 26.0 m/s

Final velocity, v = 0 m/s

Distance travelled, s = 120m

Using

v² = u² + 2as

0 = 26² + 2(120)a

a= -2.82 m/s²

Velocity of the car when it was 60.0m past the point where the brakes were applied:

u = 26.0 m/s

a = -2.82 m/s²

s = 60m

Using

v² = u² + 2as

v² = 26² + 2(-2.82)(60)

v² = 337.6

v = 18.4 m/s
