Question

5kg mass of bock is over the 4m surface and work done by the force is 250j so what is work done by the friction

Answer 1

here total work done = 250

work done by gravity + work done by friction = 250j

mgh + work done by friction = 250joule

5*4*10+ work done by friction = 250

work done by friction = 250-200

work done by friction = 50 joules
