VIDEO EXPLANATION

ANSWER

When a object is moving with a constant velocity, it possess K.E

K.E=

1/2 ×m×v^2

So, in order to bring the object to rest i.e its same magnitude of energy is required so, as the final final energy comes to zero.

So, magnitude of work that needs to be done =

1/2 ×m×v^2

10m/s

So, work required to stop the car =

1/2 ×1500×10^2

⇒75000
