## Homework Statement

A .5 kg loaded toy (spring k=8000 n/m) loaded toy is compressed .05 m and fired on a flat surface

a) Find the new speed it was released with

b) If it approaches a hill find the maximum height it can climb

## Homework Equations

KE=1/2kx²

KE=1/2mv²

PE=1/2kx^2

## The Attempt at a Solution

a) KE= 1/2(8000N/m)(.05m)²

KE=200J

KE=1/2mv²

200J=1/2(.5kg) v²

v= 28.284 m/s

b) PE=1/2kx^2

PE=10J

PE=mgh

10=.5kg(9.8m/s²)x

2.04m=h
