A 416 N force is pulling an 87.2-kg refrigerator across a horizontal surface. The force acts at an angle of 22.0 ° above the surface. The coefficient of kinetic friction is 0.197, and the refrigerator moves a distance of 8.72 m. Find (a) the work done by the pulling force, and (b) the work done by the kinetic frictional force.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
