## Homework Statement

Kayleigh is standing on top of a 30 m high cliff shoots a 500 g arrow with a speed of 25 m/s. What is the impact speed of the arrow right before it strikes the ground below? Ignore air resistance and friction.

## Homework Equations

Et= Ek+Eg

## The Attempt at a Solution

1/2mv1^2 + mgh = 1/2mv2^2

v2^2= Square root of 2(1/2 (25m/s)^2 + (9.8 m/s^2)(30m)

vs^2= 34.82 m/s

Is my answer correct?
