Question

A boy drags a 10 kg box across the friction-less surface. He applies a force
of 30 N at an angle of 60° to the horizontal for 6m. Determine the work done.

Answer 1

using a formula

W = F×S×COS

PUT THE ALL THE VALUE IN THIS FORMULA

W=30×60degree×6

cos60 = 1/2

30×1/2×6

solve the problem

W= 90 joule
