If a seagull drops a shell from rest at a height of 13 m, how fast is the shell moving when it hits the rocks?

For this problem, we can use a kinematic formula to help us solve this. We know the given the distance, the initial velocity, and the acceleration due to gravity, which is 9.8 m/s². We want to know the final velocity.



is the final velocity
is the initial velocity
is the acceleration, in this case, the acceleration due to gravity
is the distance.









Take the square root of both sides.



That is the velocity right before the shell hits the rocks. I hope this helps! :)
