A crate of fruit with a mass of 33.5 kg and a specific heat capacity of 3750 J/(kg \cdot K) slides 7.20 m down a ramp inclined at an angle of 39.4 degrees below the horizontal.
If the crate was at rest at the top of the incline and has a speed of 2.15 m/s at the bottom, how much work W_f was done on the crate by friction?
Use 9.81 m/s^2 for the acceleration due to gravity and express your answer in joules.
