Question: A crate of fruit with mass 35.0 kg and specific heat 3650 J/kg K slides down a ramp inclined at 36.9C below the horizontal.

A crate of fruit with mass 35.0 kg and specific heat 3650 J/kg • K slides down a ramp inclined at 36.9°C below the horizontal. The ramp is 8.00 m long.
(a) If the crate was at rest at the top of the incline and has a speed of 2.50 m/s at the bottom, how much work was done on the crate by friction?
(b) If an amount of heat equal to the magnitude of the work done by friction goes into the crate of fruit and the fruit reaches a uniform final temperature, what is its temperature change?
