Part A A crate of fruit with a mass of 38.5 kg and a specific heat capacity of 3750 J/(kg . K) slides 8.40 m down a ramp inclined at an angle of 37.5 degrees below the horizontal. If the crate was at rest at the top of the incline and has a speed of 2.60 m/s at the bottom, how much work W was done on the crate by friction? Use 9.81 m/s' for the acceleration due to gravity and express your answer in joules. View Available Hint(s) AEQ Wf = Submit Part B Complete previous part(s)
