Suppose a 24.4 kg block of aluminum (c = 900 J/(kg⋅∘C)) is being pushed down a steep ramp that is inclined at an angle of 65∘ from the horizontal by a 133 N force directed vertically straight down on the block. The surface of the ramp is so rough that the block moves with a constant velocity of 4.2 m/s for a distance of 103 m down the length of the ramp. You may assume that no heat is lost to the environment.

If the block has a temperature of 24∘C at the top of the ramp, what is the temperature of the block when it reaches the bottom of the ramp?
