(1)It takes a force of 75 N to compress the spring of a toy popgun 0.18 m to "load" a 0.14 kg ball. With what speed will the ball leave the gun?

I used the equation F=kx

I solved for K and I got 416 N/m

Then I used the equation omega = square root(K/M)

I solved for omega and i got 54.5.

Is this correct? It seems wrong to me. Please help, any suggestions will be greatly appreciated.
