A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity
of 185 feet per second from an initial height of 128 feet off the ground, then the height of the projectile,
h, in feet, t seconds after it's shot is given by the equation:

h=-16t2+185t + 128

Find the two points in time when the object is 161 feet above the ground.
