A projectile is fired straight upward from the ground level with an initial velocity of 112112112 feet per second, so that its height h at any time t is given by h=−16t2+112th = - 16 t ^ { 2 } + 112 th=−16t2+112t , where h is measured in feet and t is measured in seconds. During what interval(s) of time with the height of the projectile exceed 160160160 feet?
