Pendulum collision Two balls of clay, each of the same mass m, are suspended by two strings. We pull one of them back to the left as shown, so that it is a height h above where it would hang at rest, and we let it go to swing from there. After the collision they swing together When it hits the other ball the two stick together into a lump of mass 2m. What could we take to be conserved in the instant of the collision? Consider i. Momentum P: Pim = P2m ii. Kinetic energy KE: KE = KE iii. Angular velocity w (around the pivot): w, = w, iv. Angular momentum L (around the pivot): L=12 A. p only B. KE only C. p and KE D. p and L E. p and w F. p, L, and w
