Question

A 1500 kg car stops with total retardation of 4 m/s². Braking force is 4500 N. What is the frictional retardation?

Options

• 1 m/s²

• 4 m/s²

• 5 m/s²

• 3 m/s²

Answer 1

1 m/s²

Explanation:

This is found by subtracting the braking retardation (3 m/s2) from the total retardation (4 m/s2).
