a.) What is the magnitude of the objects acceleration after it isreleased(relative to the ground)?
b.) How long does it take it to hit the ground?

During liftoff, a hot-air balloon accelerates upward at a rate of3.2 m/s^2. The balloonist drops an object over the side of thegondola when the speed is 18 m/s.


How long does it take to hit the ground?
What I've been trying is using the x(t) = -1/2at^2 + V0t + X0formula, where I would plug in g = 9.8 for a, and V0 = 0. Then Iset x(t) to 0 and solved for t where I get: sqrt(2X0/g) = t. Thisis where I get stuck, I don't know what X0 is since the problemonly gives limited information, how do I find X0? I tried pluggingin 18 for it, but that's the velocity of where the object wasdropped.
