A crate of fruit with a mass of 35.5 kg and a specific heat capacity of 3650 J/(kg⋅K) slides 8.20 m down a ramp inclined at an angle of 36.3 degrees below the horizontal.
Part A
If the crate was at rest at the top of the incline and has a speed of 2.40 m/s at the bottom, how much work Wf was done on the crate by friction? Use 9.81 m/s^2 r for the acceleration due to gravity and express your answer in joules.
Part B (if answer for part A is -1590J)
If an amount of heat equa to the magnitude of the work done by friction is absorbed by the crate of fruit and the fruit reaches a uniform final temperature, what is its temperature change ΔT
