Question

How do you calculate the work done on a block ofmass 1.1 kg by the rope when it is being pulled upwards by arope attached to a heavier block with a mass of 3.0 and the kineticfriction co-efficient between m1 and the tabletop is 0.25 (mass 1is on a table and moving to the left, mass 2 is hanging off theright side of the table and being pulled upwards) Any help would be greatly appreciated!

Explanation / Answer

W = m1 g s + m2 g h W = ( m1 + m2 ) gh   since h = s where s is the distancem1 moves on the table
