# Question: A car with a mass of 1500 kg is rolling

A car with a mass of 1500 kg is rolling on a level road at 30.0 m/s. It receives an impulse with a magnitude of 2000 N ∙ s and its speed is reduced as much as possible by an impulse of this size.

(a) Was this impulse caused by (1) the driver hitting the accelerator, (2) the driver putting on the brakes, or (3) the driver turning the steering wheel?

(b) What was the car’s speed after the impulse was applied?
