1.) After how many seconds will the balloon hit the ground? (hint: Use the quadratic formula)

Answer: 1.67 sec

Answer 1

The balloon is thrown up, and reaches a maximum height.
Then it starts falling until it hits the ground.

When the balloon hits the ground on its way down, what height is it at?
