In how many seconds will the projectile strike the ground?

A projectile is fired with an initial velocity of 500 feet per second at an angle of 45° with the horizontal. In how
many seconds will the projectile strike the ground? (Round your answer to the nearest tenth of a second.) The
parametric equations for the path of the projectile are:

x = (500 cos 45°)t, and
y = (500 sin 45°)t - 16t2.
 
What formula would you use?
