Question

A body of mass 2kg initially at rest moves under the action of an applied force of 7N on a table with coefficient of kinetic friction = 0.1. Calculate the 

(1) Work done by the applied force in 10s 

(2) Work done by the friction in 10s 

(3) Work done by the net force on the body in 10s. 

Answer 1

Here m = 2kg U = 0, F = 8N µ = 0.1 W = ? t = 10s
