Question 1158922: A car and a truck collide on the highway. The truck is 4 times as massive as the car. The car has an initial velocity of 40msSouth and a final velocity of 0. The collision takes place over 1 second. If the truck also ends up with a velocity of 0 after the collision, what was its initial velocity?

You can put this solution on YOUR website! .
Use the momentum conservation law, which for this problem has the form
m*v = M*V
Do the rest on your own.
The collision time is IRRELEVANT in this problem.
