Question

3. A car of mass 500 kg is moving on a straight
road with constant velocity of 20 ms-1. Force
required to move the car with the above velocity
(1) 20 x 500 N
(3) 250 N
(4) Zero
​

Answer 1

Answer:

Zero

Explanation:

In a uniform motion (constant velocity motion) no force is required to maintain the motion.

On application of force, body gets accelerated (a = F/m) and will be no more in uniform motion.
