Initial velocity=√(2gh)
h=height reached.
Spring constant=k
compression = x = 0.125m
Potential energy=(1/2)mv²=mgh
=(1/2)kx²
solve for k in
(1/2)kx² = mgh
k=2gh/x²
A dart gun where you compress the spring and it shoots a rubber dart of a mass 0.122 kg. The dart is shot vertically and gains 2.50 m.
a) what speed did the dart leave the toy gun?
b) If the spring is compressed 0.125 m what is the elasticity coefficient of the spring?

What happen to the m? It cancelled out?
Yes, but only in the first part.
m was inadvertently omitted in the second part, my apologies.
k=2mgh/x²

Thank you!
You're welcome! :)
