Question

A projectile is launched from ground level with an initial velocity of $v_0$ feet per second. Neglecting air resistance, its height in feet $t$ seconds after launch is given by $s = -16t^2 + v_0t$. Find the time(s) that the projectile will (a) reach a height of 160 ft and (b) return to the ground when $v_0 = 112$ feet per second.
