The total work done by friction on the block as it slides down the ramp is 44 J.
The given parameters;
mass of the block, m = 2 kgheight of the ramp, h = 3.0 mkinetic of the block, K.E = 50 JThe work done by friction is the change in the mechanical energy of block;
Thus, the total work done by friction on the block as it slides down the ramp is 44 J.
