An 80 kg block sits on top of a hill with height h1 = 3 metres and slides down to a 3 metres long muddy flat section with a coefficient of kinetic friction, μk = 0.20. The block continues up the frictionless ramp with an angle of θ = 45°. What is the velocity of the block in m/s at the bottom of the first hill?How much energy is ‘lost’ by the block during the muddy section (answer in Joules)?What height, h2, in metres does the block reach up the ramp after the muddy section before coming to a complete stop?Now consider the ramp after the muddy section to have a coefficient of kinetic friction, μk = 0.3. What height does the block reach in metres?
