Question

A car slows down from 50.0 m/s to 20.0 m/s in 6.0 s. What is the acceleration?

Answer 1

Use this formula: Acceleration = Change in velocity/Time

Given in the question:

Change in velocity - 50 - 20 = 30 m/s

Time - 6 seconds

Calculation

Acceleration = Change in velocity/Time

= 30/6

= 5 m/s

Therefore, the acceleration is 5 m/s.
