just conserve momentum:
2900<34,0,0> + 4800<-18,0,28> = (2900+4800)v
<98600,0,0>+<-86400,0,134400> = 7700v
<12200,0,134400> = 7700v
v = <1.58,0,17.45>
A car of mass 2900 kg collides with a truck of mass 4800 kg, and just after the collision the car and truck slide along, stuck together. The car's velocity just before the collision was < 34, 0, 0 > m/s, and the truck's velocity just before the collision was < -18, 0, 28 > m/s
(a) What is the velocity of the stuck-together car and truck just after the collision?
