K19.4+ Eccentric Impact 4 of 20 rot - 5.661x10-2 kg-m2 Learning Goal evious Answer To be able to use the relationship between the velocities of two colliding objects and the coefficient of restitution to describe a collision. Correct Eccentric impact occurs when the line connecting the mass centers of two bodies does not coincide with the line of impact. In a collision between two bodies A and B assuming that the initial velocities (vA)1 and (vB)1 along the line of impact are known, there are two unknowns: the final velocities (vA)2 and (vB)2 Because there are two unknowns, there must be two equations. The first equation involves the conservation of angular and linear momentum of the bodies. The second Part B As shown, a baseball of mass 145 g is thrown at the target. (Figure 2) The ball hits the target at a vertical distance h 28.5 cm from the pin at point O with a speed of (vA)\ -11.4 m/s perpendicular to the target. If the coefficient of restitution between the ball and the target is e- 0.520, what is w, the target's angular velocity immediately after the ball hits the target?
