work = FS cos theta

= 200 * 1*cos60

= 200*1/2 = 100

The work done by the roller is 10^5\ J.

Explanation:

It is given that,

Force acting on the roller, F = 200 N

Distance, displaced by the roller, d = 1 km = 1000 m

Angle with lawn, \theta=60^{\circ}

We need to find the work done. We know that the work done is the product of force and displacement. It is given by :

W=Fd\ cos\theta

W=200\ N\times 1000\ m\ cos(60)

W=10^5\ J

So, the work done by the roller is 10^5\ J. Hence, this is the required solution.
