a train car traveling at 5.0m/s with a mass of 1000 kg collides and sticks to a stationary train car with mass?
a train car traveling at 5.0m/s with a mass of 1000 kg collides and sticks to a stationary train car with mass of 2000kg.
A) How fast will the two attached cars be traveling after the collision?
B) If they collide with a wall where does the momentun go?
for a. use formula for inelastic collision
m1v1+m2v2=vf(m1+m2)
since the second car is initially at rest the m2v2 is zero
so the final velocity is equal to
vf=(m1v1)/(m1+m2)
just substitute in the unknowns to get the answer.
b. the momentum is transfered into the wall.
