do you recall the equations for x(t) and y(t) ??

i am not sure of which equations to use

is it x= x= x0+Vx0t-1/2gt^2?

yes that was for y not x

is x0 the 7.68?

i am confused about which numbers are what variables

and xt?

so i have to figure out the y component first?

our unknows here are v0 and t, so we must solve the system for both of them.

so the equation would be Vo(t)-1/2gt^2?

1/2gt-Vsin(33.4)??

t=2Vsin(33.4)/g??
