Question

(a) A force of 1000N was applied to
stop a car that was moving with a
constant velocity. The car stopped
after moving through 10m. How
much is the work done?


did you know the answer
​

Answer 1

Answer:

If a object is moving with constant speed that means the velocity will not change with the time. Hence, If a body is moving with constant speed, its acceleration is must be zero.

Explanation: i hope this helps you

Answer 2

Explanation:

Work done by the force to stop the car = Force applied on the car × Distance covered by it after the force applied.

∴ W = 10000 J. or W = 10 kJ.

Hence, the work done by the force to stop the car is 10 kJ (or kilo Joule) or 10000 J.
