Question

A car slows down from a speed of 20m/s to rest in 25 seconds. What is the acceleration of the car in m/s

Answer 1

Answer:.8

Explanation:

Answer 2

Explanation:

1. The formula to find acceleration=difference between final and initial velocities/time taken
2. the initial velocity is 20 m/s
3. as it comes to rest,the final velocity is 0
4. the time taken is 25s.
5. then acceleration is 20-0/25 =20/25=0.8m/s*2
