Calculate the amount of work required to stop a car of 1000 kg moving with a speed of 72 km/h 2​

Answer»

Answer:

EXPLANATION:

Here ,

Initial Velocity = U = 72 km/h = 20m/s

Final Velocity = V = 0 m/s

Mass of the body = m = 1000 kg

Now using the concept of Work Energy Theorem :

Work Done = ½mv²-½mu² = 0-½×1000×20 = 10000 N

The total work done is 10000 N.
