Homework Statement
Two vehicles approach a right angle intersection and then collide. After the collision, they become entangled. If their mass ratios were 1:4 and their respective speeds as they approached were both 13 m/s, find the magnitude and direction of the final velocity of the wreck.
A)16.3 m/s at 79° B)13.1 m/s at 79° C)15.7 m/s at 79° D)12.5 m/s at 79°
Homework Equations
p=mv. m1v1+m2v2=(m1+m2)vf
The Attempt at a Solution
i found both x and y compontents of the cars, with one car having a mass of 1 kg and another having a mass of 4kg. I ended up getting, 10.7m/s and 76 degrees, but that is not even a choice
