Ablock of mass 0.84 kg is suspended by a string which is wrapped so that it is at a radius of 0.061 m from the center of a pulley. the moment of inertia of the pulley is 6.20 times 10^-3 kg m^2. there is friction as the pulley turns. the block starts from rest, and its speed after it has traveled downwards a distance of d= 0.65 m, is 1.705 m/s. calculate the amount of energy dissipated up to that point.
a) 5.620 times 10^-1
b) 8.150 times 10^-1
c) 1.182
d) 1.713
e) 2.484
f) 3.603
g) 5.224
h) 7.574
