Question
An object of mass m = 3 kg is released from rest at the top of a frictionless inclined
plane at point A. It reaches the bottom of the incline at point B with a velocity vg. It
then continues along a rough horizontal path of length BC = 4m where the
coefficient of kinetic friction is μ = 0.1. If the net work applied on the object along
the inclined plane is Wnet (A-B) = 20 J, then what would the speed of the object be
at point C?
Take g = 10 m/s².
