find rate of energy being dissipated by the frictional force?

Question

You push a 34.4 kg crate at a constant speed of 1.66 m/s across a horizontal floor with coefficient of kinetic friction 0.34. The acceleration of gravity is 9.8 m/s^2.
a) At what rate is work being done on the crate by you?
b) At what rate is energy being dissipated by the frictional force?

I found the answer to a) which was 190.23 W. But I don't know what to do for part b. Please help!!

Answer 1

The answer to b is the same as a. You're doing this work on the crate and it isn't accelerating so it isn't gaining energy. Your work is all being dissipated by the friction!
