A4 kg bowling ball begins rolling down a at bowling alloy at 6 m/s . When it strikes the pins, it is estimated to be moving at 5 m/s . How much onergy is lost due to friction?

Energy lost due to friction is 22 J      

Explanation:

Mass of the ball m = 4 kg

Initially velocity of ball v = 6 m/sec

So kinetic energy of the ball

Now due to friction velocity decreases to 5 m/sec

Kinetic energy become

Therefore energy lost due to friction = 72 -50 = 22 J
