## Homework Statement

A 200 kg object moves at 10 m/s at 20m (vertically). It falls to a height of 5 m. Find the new speed.

## Homework Equations

vf²=vi²+2ad

## The Attempt at a Solution

vf²=(10m/s)²+2(9.8m/s²)(15m)

vf=19.8m/s

To find the distance for the new speed I did 20-5, but I'm not sure it's correct.

Also I'm not sure if I'm supposed to use 9.8 for the acceleration
