Question

If a car is moving northwards and the driver jams on its brakes, the direction of its acceleration is ____.

Answer 1

1. Acceleration is defined as the rate of change in velocity with respect to the time taken.
2. Here, the driver applies the brake when he is in the north direction.
3. So, when he applies a brake the direction of acceleration is reversed as deceleration occurs.

Thus, from the north direction due to the brakes, the car's acceleration is towards the south direction.
