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
