PLEASE HELP: A 1400 kg car moving +13.7 m/s makes an elastic collision with a 3200 kg truck, initially at rest. What is the velocity of the truck after the collision? (Unit = m/s) remember: right is +,

Answer:


8.339\ m/s

Step-by-step explanation:

Given :


m1= 1400 kg \\v1=13.7 m/s\\m2=3200 kg \\v2=0

We know that for the elastic collision


V2=(2m1v1)/(m1+m2) \ + (m2-m1 * v2)/(m1+m2)

Putting the respective value we get


V2=(2*1400*13.7)/(1400+3200) \ + 0\\ V2=8.339\ m/s
