Actually, this is a problem in my calc book. I'm supposed to solve it using parametric equations but I figured its still physics...

Using parametrics: the

x(t)=x

_{0}+h

_{0}t

x(t)=90t

y(t)=(-1/2)gt

^{2}+v

_{0t+yo y(t)=-16t2+47t+3 Using physics: Not sure which equation to use. I'm a little confused. I started by adding the velocity vectors, and got 101.5 ft/s in an upwards diagonal direction I used v2=v02+2ax v=0, v0=101.5, solved for x and got 525.625. answer should be 270. no idea what to do..... I'd prefer to work with the parametric method but any help is welcome....Thanks}
