Question

A 100 kg car starts from 20 m/s and speeds up to 41 m/s in 7 seconds. Determine the car's

acceleration.

Answer 1

Answer: 3 m/s^2

Step-by-step explanation:

Acceleration equals change in velocity (speed) divided by total time.

a = (v2-v1)/t

a = (41 m/s - 20 m/s) / 7 s

a = 3 m/s^2

Mass is irrelevant in this question.
