Solution :-
Given data:
The mass of the body = 1500 kg
Velocity v = 60 km/hr
\( = \frac{60\,\times\,100m}{3600s}\)
\( = \frac{50}{3}\,m/s\)
The work required to stop the car = kinetic energy change of the car
\( = \frac{1}{2}\,mv^2\,-\, \frac{1}{2}m(0)^2\)
\( = \frac{1}{2}\,\times\,(1500)\,\times(\frac{50}{3})^2\)

Soni says that the acceleration in an object could be zero even when several forces are acting on it. Do you agree with her? Why?
In each of the following a force, F is acting on an object of mass, m. The direction of displacement is from west to east shown by the longer arrow. Observe the diagrams carefully and state whether the work done by the force is negative, positive
