Presentation transcript:

Particle Impact: Ex Prob 2 (Semi-Oblique) For the impact problem shown below, please determine the velocities of particles A and B after impact. (A and B are identical, thus mass A = mass B) Think! It seems that v B2 will be at some angle as shown. What about v A2 ?

Identify Plane of Contact, Line of Impact, and resolve vectors into components. What about v A2 ? If there is no impulse of friction along the plane of contact, then no y momentum can be imparted to A. So, v A2 will act along the x axis. It’s y component will remain zero. (That’s why I call this a “semi-oblique” problem.)
