Q4. A cylindrical barrel of mass 200 kg starts from rest at the top of a ramp 5 metres tall. At the base of the ramp, the cylinder is moving with a linear velocity of 8 m/s. a) Calculate the moment of inertia for the barrel, modelling it as a uniform cylinder with a circular face of diameter 75 cm. b) By considering the conservation of energy during the barrel's travel, find the rotational speed of the barrel when it reaches the bottom of the ramp. Give your answer in rotations-per-minute (RPM). (2) (5) (7 marks)
