Hello, I am currently taking AP physics and require some assistance with a problem. I have to find the magnitude and angle of the original velocity of a projectile, normally this would be no problem for me but the original height is not zero which is giving me some problems.(adsbygoogle = window.adsbygoogle || []).push({});

My givens are:

t= 4.5s

dx= 45m

h= 1.6m

I believe I can get the x component with:

delta x=vox t +1/2gt**2

45m=vox(4.5s) + 4.905(4.5s**2)

so vox= .4334

If I did the above correctly all I would need now would be the y component, the problem is I have no idea on how to find it.

Any assistance would be greatly appreciated.
