Question

A car traveling at 25 m/s starts to decelerate steadily. It comes to a complete stop in 5.5 seconds. What is the car’s acceleration?

Answer 1

4.5 m/s

Explanation:

acceleration is the change in velocity divided by time. so, 25 m/s going to 0 m/s (stop), which is 25, divided by 5.5 seconds is 4.5 m/s
