A7.00- kg bowling ball moves at 3.00 m/s. how fast musta
2.45- g ping pong ball move so that the two balls have the
samekinetic energy?

Ping Pong ball move at velocity 160.4 m/s

Explanation:

given data

mass m1 = 7 kg

velocity v1 = 3 m/s

mas m2 = 2.45 g = 2.45 × kg

same kinetic energy

to find out

How fast Ping Pong ball move (v2)

solution

we know same KE

so

  ...........1

so v2 will be

v2 =    .............2

put here value in equation 2 we get v2

v2 =

v2 = 160.4

so Ping Pong ball move at velocity 160.4 m/s
