Question

A car accelerates from rest to 25 miles per hour in 3.0 seconds. What was the car's

acceleration?

Answer 1

The car's acceleration was 3.73 metre per second square = 3.73m/s²

Explanation:

The car accelerated from rest.

initial velocity (u) = 0m/s

final velocity (v) = 25miles/hr = 11.2m/s

time (t) = 3s

a = ?

v = u+at

a = (v-u)/t

a = (11.2 - 0) / 3

a = 11.2/3

a = 3.73

a = 3.73m/s²
