- 80

- 0

anyway, I'm trying to use the formula

Fspring = -Kx k is the constant.

I think xf - xi = .04m - 0m = .04 = x

I don't know how to get the force though... I split it as F=ma

then I know the mass.. .150kg, but I don't know how I can get the acceleration from the 25.0 rev/s

I'm confused [b(] Can someone help me!!!!?? =)
