A car possesses 20,000 units of momentum, whats the cars momentum if its velocity is doubled? tripled?

##4000## if doubled, ##6000## if tripled

Momentum=velocity x mass ##(mn =mv)## For initial stage ##mn = mv = 2000##

if the speed is doubled ##mn = m x 2v = 2 x mv = 2 x 2000 = 4000##

similarly if the speed is tripled the momentum will be ##3 x 2000 = 6000##
