Question

To slow down a car ,a braking force of 1200 N

Answer 1

Explanation:

Slow down a car braking force of 1200 newton is applied for 10 second how much force would be needed to produce the same change in velocity in 6 seconds. A certain force exerted for 1.2s raises the speed of an object from 1.8m/s to 4.2m/s. Later, the same force is applied for 2seconds.
