1.	A man pulls a trolley a distance of 20 m on a smooth surface if the force applied by the man is 30 n then calculate the work done in pulling the troley.
Answer» r,◆ ANSWER -W = 600 J◆ Explaination-# Given-F = 30 Ns = 20 mθ = 0°# Solution-As the surface is smooth there will be no frictional force.Work done by force in displacing TROLLEY is calculated by-W = F.sW = FscosθW = 30 × 20 × cos(0°)W = 600 JTherefore, work done by force in pulling the trolley is 600 J.Hope this HELPS...
