Option 1: A mass of 40kg starts from rest on a frictionless incline that is at an angle of 30 to the horizontal. It slides down the ramp 60m to the bottom and has a completely inelastic collision with a stationary 30kg mass. The two masses then slide across a rough area with a coefficient of kinetic friction 0.20. a) Draw a diagram of the situation. Labelling all relevant variables given in the question and used during solving [1 mark] b) Find the final velocity of the 40kg box at the bottom of the ramp [3 marks] c) How far do the two masses move across the horizontal rough area before coming to a rest?
