Car is traveling at a speed, what speed will a truck have the same momentum?

[IDKPhysics101]

A car with a mass of 964.0 kg is traveling at a speed of 63.3 km/hr. At what speed (in km/hr) will a 3530.7 kg truck have the same amount of momentum as the car?

A car with a mass of 964.0 kg is traveling at a speed of 63.3 km/hr. At what speed (in km/hr) will a 3530.7 kg truck have the same amount of momentum as the car?

First start by asking yourself what is the definition of linear momentum and hence what is the momentum of the car?

car
speed=63.3km/hr=17.58m/s
p=964*17.58
p=16947.12

truck
p=mv
16947.12=3530.7*V
V=4.79m/s??

Yes, that should be correct.
