A 40 kg box is placed on a frictionless ramp at 20 to the horizontal. 1) Draw a diagram of this identifying the relevant forces: force due to gravity, forces normal and tangential to the ramp. (4 Marks) 2) What is the magnitude of the force on the box normal to the surface? (3 Marks) 3) Calculate the tangential force and hence the acceleration of the box down the ramp. (3 Marks)
