Question

What is the momentum of a 47-gram tennis ball that is traveling at 40 m/s

Answer 1

Momentum is defined as the product of mass and velocity

so here we have

mass = 47 gram = 0.047 kg

velocity = 40 m/s

now we have

$P = mv$

$P = (0.047)(40 kg m/s$

now we have

$P = 1.88 kg m/s$

so here the momentum will be 1.88 kg m/s
