A 900 kg car is traveling at 15 m/s when it suddenly collides with a 750 kg car traveling north at 20 m/s. The cars stick together after the collision. What is the speed of the wreckage just after the collision?
Homework Answers
m1*u1 + m2*u2 = (m1+m2)*V..
final speed is V = [(m1*u1)+(m2*u2)]/(m1+m2) =
[(900*15)+(750*20)]/(900+750)...
V = 17.27 m/sec

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 20.9 m/s and a 1500 kg pickup
is traveling north toward the same intersection. The car and truck
collide at the intersection and stick together. After the
collision, the wreckage (car and truck) moves off in a direction of
44.0° above the x-axis. Determine the initial speed of the truck
and the final speed of the wreckage in meters...
