"A 10 m long frictionless ramp is inclined at an angle of 30 degrees to the horizontal. A boy of mass 57 kg coasts down the incline on a skateboard of mass 3.0 kg. The acceleration due to gravity may be taken as 9.8 m/s^2 and the effects of air resistance can be ignored. Calculate the magnitude of the normal force acting on the skateboard and the rider."
