QUESTION:
In Fig. 8.22b, the kinetic energy of the Ping-Pong ball is larger after its interaction with the bowling ball than before. From where does the extra energy come? Describe the event in terms of conservation of energy.
ANSWER:Solution 13DQ Step 1 of 3: Before collision the the bowling ball of mass M was moving with speed v and the ping b1 pong ball is at rest with velocity zero v = 0 as shown in the figure below, p1 The energy of the system before collision, E 1 Kinetic energy of bowling ball + potential energy of ping pong ball E1= mv2 2 + PE ………….1 b1
