Question

1800 kg object was moving to the east at 13 m/s, collided with a 200 KG object that was moving to the north at 32 m/s. What was the magnitude of the velocity after the collision assuming it was inelastic

Answer 1

`\begin{gathered} For\text{ object moving to the east} \\ m1=1800kg \\ v1=13m/s \\ For\text{ object moving to the north} \\ m2=200kg \\ v2=32m/s \\ v=? \\ v=(m1v1+m2v2)/(m1+m2) \\ v=((1800kg)(13m/s)+(200kg)(32m/s))/(1800kg+200kg) \\ v=14.9m/s \\ The\text{ velocity after the collision is 14.9m/s} \end{gathered}`
