A rock is thrown horizontally from a bridge with a velocity of 16.0 m/s. It takes the rock 3.20 s to strike the water below. What is the magnitude of the velocity of the rock just before it hits the water?
Added by Scott B.
Step 1
0 m/s - Time of flight (\(t\)) = 3.20 s - Initial vertical velocity (\(v_{y0}\)) = 0 m/s (since the rock is thrown horizontally) - Acceleration due to gravity (\(g\)) = 9.8 m/s² Show more…

A ball is thrown vertically upward from the edge of a bridge 20.0 m high with an initial speed of 16.0 m/s. The ball falls all the way down and strikes the water below. Determine the magnitude of the velocity of the ball just before it strike the water.

A rock is thrown from a bridge 17.5 m above water with an initial speed of 16 m/s. Assuming negligible air resistance, what is the speed that the rock hits the water with, in meters per second? vf = |

You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 6.00 s after it was thrown. What is the speed of the rock just before it reaches the water 28.0 m below the point where the rock left your hand? Ignore air resistance.
