(N/A) The work done $(W)$ by a force is defined by the formula $W = F \cdot s \cdot \cos(\theta)$,where $F$ is the force,$s$ is the displacement,and $\theta$ is the angle between the force and displacement vectors.
Therefore,the work done depends on the following three factors:
$(i)$ The magnitude of the force $(F)$ applied to the object.
$(ii)$ The magnitude of the displacement $(s)$ produced in the object.
$(iii)$ The angle $(\theta)$ between the direction of the applied force and the direction of the displacement.

An automobile engine propels a $1000 \,kg$ car $(A)$ along a levelled road at a speed of $36 \,km \,h^{-1}$. Find the power if the opposing frictional force is $100 \,N$. Now,suppose after travelling a distance of $200 \,m$,this car collides with another stationary car $(B)$ of the same mass and comes to rest. Let its engine also stop at the same time. Now car $(B)$ starts moving on the same level road without its engine started. Find the speed of the car $(B)$ just after the collision.
