Question

How fast would a 5.0×20³kg golf ball have to travel to have the same momentum as 5.0kg bowling ball that is rolling at 6.0m/s[forward]

Answer 1

Explanation:

I think you were saying the mass of the golfing ball is 5.0x20^-3 because a golfing ball can't be too heavy because 5.0x20³ = 40,000kg!!

Mass of the golf ball=5*20^-3= 0.000625kg

Mass of the bowling ball= 5kg

Velocity of the bowling ball= 6m/s

Momentum of the bowling ball= 5*6

= 30kg.m/s

Therefore, as Momentum of Golfing ball= Momentum of the bowling ball, so the velocity of the golf ball is,

0.000625*V=30

V=30/0.000625

V=48,000m/s
