12) A 317 kg piano is at the top of a ramp that makes an angle of 18 with the level ground. As the piano slides down the ramp, it experiences a force of friction. The coefficient of kinetic friction is 0.225. What is the acceleration of the piano down the ramp? (6 marks)

13) A bucket filled with water, with a combined mass of 3120 g, is attached to a 0.75 m rope and swung in vertical circle. What is the slowest speed the bucket can be spun at while maintaining uniform circular motion, and at that speed what is the force of tension in the rope at the bottom of the circle?
