work out momentum of each vehicle before the collision!

so say A is the car, A has momentum 32 x 1070

so B is the SUV, and has momentum -v x 2390 (- v because in opposite direction to A's velocity)

so the total momentum is (32 x 1070) - (v x 2390)

now work out momentum after collision

as they come to a hault, then the velocity is zero, and assuming they stay together, the the masses can be added.

so final momentum is 0 x 3460

now put into an equation, because of the conservation of momentum law

we have,

(32 x 1070) - (v x 2390) = 0 x 3460

so after calculation

v = 14.326 m/s
