Homework Statement
A rock is thrown horizontally from a bridge at a speed of 32.6 m/s. If the rock is 32.0 meters above the river at the moment of release, find how long the rock is in the air? 2.56 seconds. Find the horizontal distance to the point of impact from the point of release? 83.31 meters
Find the speed with which the rock strikes the river? I don't know
Homework Equations
V=Sq root of(vx^2 + vy^2)
Vox = Vx
X=VoxT
Vy=Voy + at
y=voyt + 1/2at^2
Vy^2 = Voy^2 + 2ay
The Attempt at a Solution
MY HINT:Apparently this is a vector problem. "Add" horizontal and vertical velocities. So i added the horizontal velocity that was 32.6...but what's the vertical velocity?
