You lift a 450 N bag of rice 1.2 metres and carry it a distance of 10 metres to the kitchen. How much work is done?

W=F.S Cos(theta)

We have to know the 'THETA' Which is point of application of force

In this case, Only Force and displacement , there is no use of length of sack

Simply if we take W=F.S and Cos180°= (-1) So,W=450x 10x (-1) =(-4500) Adarsh Mahor · 9 months, 2 weeks ago

Work done will be zero as the angle between force (in verticle direction against gravity) and displacement (if kitchen is in same horizontal plane) is 90. Aman Dubey · 9 months, 2 weeks ago
