Abowling ball of mass 88.8kg moves in a straight line at 1.45m/s how fast must a ping pong ball of mass of 2.537g move in a straight line so that the two balls have the same momentum

M = mass of the bowling ball = 88.8 kg

V = speed of bowling ball = 1.45 m/s

P = magnitude of momentum of bowling ball = ?

magnitude of momentum of bowling ball is given as

P = MV

inserting the values

P = 88.8 x 1.45

P = 128.8 J

m = mass of ping-pong ball = 2.537 g = 2.537 x 10⁻³ kg

v = speed of the ping-pong ball = ?

p = magnitude of momentum of ping-pong ball

Given that :

magnitude of momentum of ping-pong ball  =  magnitude of momentum of bowling ball

p = P

m v = 128.8

(2.537 x 10⁻³) v = 128.8

v = 5.1 x 10⁴ m/s

scientific laws are the result of testing theories and proving them to be facts.
