# Friction and Temperature Change Situation

Not what you're looking for?

A crate of fruit with a mass of 35.0 kg and a specific heat capacity of 3800 J/kg.K slides 8.30m down a ramp inclined at an angle of 40.0 degrees below the horizontal (acceleration due to gravity is 9.81m/s^2).

If the crate was at rest at the top of the incline and has a speed of 2.40m/s at the bottom, the work (W_f) done on the crate, by friction is -1730J (The frictional force opposes the motion of the crate, so the work done on the crate by friction must be a negative quantity).

If an amount of heat equal 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 ("deltaT") ?

"deltaT" = ___________________________________________ oC
