Homework Statement
A gull is flying horizontally 8.00 m above the ground at 6.00 m/s. The bird is carrying a clam in its beak and plans to crack the clamshell by dropping it on some rocks below. Ignoring air resistance, a. what is the horizontal distance to the rocks at the moment that the gull should let go of the clam? b. With what speed relative to the rock sdoes the clam smash into the rocks? c. With what speed relative to the gull does the clam smash into the rocks?
Homework Equations
I. y = y0 + Voy*T - .5gt^2
II. Vy = Voy - gt
The Attempt at a Solution
I figured out part A by first finding the time from equation I(because Voy is zero and y is zero), and then taking the time and multiplying it by the relative velocity of the gull. For part B and C, I am not sure if equation II. is needed. I've tried solving it for the final speed. But if they ask for speed, which is total distance / time, would you need a velocity equation? Since this is projectile motion(free fall), I can't think of what else to do. I'm not sure if any vector calculations are necessary. Any suggestions would be great. Thanks.
