Question

A car is traveling at a steady speed of 75 m/s and its velocity changes to 95 m/s in 10 s. What is its acceleration?

Answer 1

A car is traveling at a steady speed of 75 m/s and its velocity changes to 95 m/s in 10 s. What is its acceleration?

Acceleration is defined as the change in velocity/speed over the change in time.

1. Change in Speed: 75-95 = -20m/s
2. Change in Time: 10s

-20m/s / 10s = -2 m/s²

^{This just means for every second the car is slowing down 2 m/s.}
