projectile is fired w/an angle of 28.0degrees above the horizontal and from height 46.0m agove the ground. the projectile strikes ground w/a speed of 1.95xVo. Find Vo(adsbygoogle = window.adsbygoogle || []).push({});

I started using the eqution

(Vfy)^2=(Voy)^2+2*Ay*(delta Y)

Voy=Vosin(theta)=.47Vo

Vfy=1.954*Vosin(theta)=.92Vo

(.92Vo)^2=(.47Vo)^2+(2*-9.8*-46)

Vo=37.9

but my answer is wrong and I can't think of another way to answer the problem.....Any ideas?

Thanks for your time!
