Problem 15.79
2 of 3
I Review
The two disks A and B have a mass of 4 kg and
5 kg , respectively. They collide with the initial velocities
shown. The coefficient of restitution is e = 0.7. Suppose
that (v4)1 = 6 m/s, (vB)1 = 8 m/s. (Figure 1)
▼
Part A
Determine the magnitude of the velocity of A just after impact.
