An eagle (mA = 4.3 kg) moving with speed vA = 7.8 m/s is on a collision course with a second eagle (mB = 5.6 kg) moving at vB = 10.2 m/s in a direction perpendicular to the first. After they collide, they hold onto one another.
(a) In what direction and with what speed are they moving after the collision?
(b) Determine the mechanical energy that is lost as a result of the collision.
