An object is released into the air at an initial height of 6 feet and an initial velocity of 30 feet per second. The object is caught at a height of 7 feet. Use the vertical motion model, h = -16t^2+vt+s, where h in the height, t is the time in motion, s is the initial height, and v is the initial velocity, to find how long the object is in motion.
