An 18 Kg Canada Goose is flying due south at a constant height of 75 m with a speed of 25m/s. She is struck by a 12 kg Bald Eagle, whose path just before collision was due north climbing at and angle of 60 above the horizontal. Immediately after the collision, the bodies of the two birds are struck together and move along a vertical path. Ignoring air resistance, how long will it take for the fowl remains to reach the ground?

cute problem!

determine the velocity vectors for each.
add the vectors to get the velocity at the instant of collision.
determine the vertical portion of the new velocity.
use simple projectile equations to determine how long until they hit the ground.
