Question
A 1500 kg car traveling at 17.6 m/s to the
south collides with a 5000 kg truck that is
initially at rest at a stoplight. The car and
truck stick together and move together after
the collision.
What is the final velocity of the two-vehicle
mass?
Answer in units of m/s

momentum before = (1500) 17.6
momentum after = (1500+5000) v
momentum after = momentum before
momentum after = (1500+5000) v
momentum after = momentum before
So basically 1500 * 17.6?
huh?
(1500)17.6/(1500+5000)
(1500)17.6/(1500+5000)
when the little car hits the stationary big truck, it slows down.
Yes, I got it. Thank you
