document.write( "Question 1066609: A projectile is launched from ground level with an initial velocity of v0 feet per second. Neglecting air resistance, its height in feet t seconds after launch is given by s=−16t^2+v0t. Find the time(s) that the projectile will (a) reach a height of 96 ft and (b) return to the ground when v0 = 112 feet per second. \n" ); document.write( "
