# Vectors and velocity: Landing speed for stone thrown from edge of a cliff

Not what you're looking for?

See attached file for a drawing.

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v(0) = 17.4 m/s. The cliff is h = 42.4 m above a flat horizontal beach. With what speed does it land?

I don't understand how the stone could land with anything but the speed of gravity. Can you explain why it lands with another speed, and generally explain how to do this problem?

##### Solution Summary

The landing speed for a stone thrown from the edge of a cliff is determined. The vectors and velocity are given. With good explanations and calculations, the problem is solved.
