A hockey puck traveling at 30m/s on smooth ice is deflected by 01 = 30° from its original direction when it collides elastically with a second identical puck at rest. The second puck acquires a velocity at 02= 60° from the the original direction of the first puck (see Fig.1). - (a) Determine the speed of the two pucks after the collision. (b) Determine the initial kinetic energy of the system. (c) Determine the final kinetic energy of the system. (d) Based on your answers to parts (b) and (c), is the collision elastic or inelastic? Before collision Hockey pucks v₂=0 At rest Figure 1: 5,' After collision 7₂
