2 birds of same mass swoop down on a mouse at an angle of 60 deg from horizontal with speed 30 m/s. They collide and stick together, what is their resultant speed?
Conservation of momentum.
The Attempt at a Solution
This was just on a test I took and I got 26 m/s but I'm thinking it should be just 30 m/s down? Or is some velocity lost during the collision?
