A 70 kilogram trunk is pushed 4.2 meter at constant speed up a 30 degree incline by a constant horizontal force. The coefficient of kinetic friction between the trunk and the incline is 0.15.
Obtain the work done by the applied horizontal force?
Obtain the work done by the weight of the trunk?
Obtain how much energy was dissipated by the frictional force acting on the trunk?
From now assume the 70 kilogram trunk is pushed 4.2 meter at constant speed up a 30 degree incline by a force along the plane. The coefficient of kinetic friction between the trunk and the incline is 0.15.
Obtain the work done by the applied force?
Obtain the work done by the weight of the trunk?
Obtain how much energy was dissipated by the frictional force acting on the trunk?
