In Example 8-10, mass m1 = 2.40 kg is connectedto mass m2 = 1.80 kg as shown. Suppose the twomasses start from rest and are moving with a speed of 2.10 m/s just before m2 hits thefloor.

(a) If the coefficient of kinetic friction isµk = 0.365, what is thedistance of travel, d, for the masses?
1 cm

2 J
(c) How much nonconservative work was done on this system?
3 J
