### Question

A sandbag is dropped from a hot air balloon that is 300 [m] above the ground and rising at a rate of 13 [m/s].

a. How long does it take for the sandbag to hit the ground?

b. How fast is the sandbag going when it hits the ground?

c. At what height is the balloon when the sandbag hits the ground? (Remember that the balloon is rising at a constant rate while the sand bag is in the air.)

### Answer #1 for Questions: A sandbag is dropped from a hot air balloon that is 300 [m] above the ground and rising at a rate of 13 [m/s].

a. How long does it take for the sandbag to hit the ground?

b. How fast is the sandbag going when it hits the ground?

c. At what height is the balloon when the sandbag hits the ground? (Remember that the balloon is rising at a constant rate while the sand bag is in the air.)

**Answer:**

*If you start with the bag stationary at 300m then drop it the bag is going to fall straight down, and its maximum height would indeed just the 300m point it started from.*

*If you start with the bag stationary at 300m then drop it the bag is going to fall straight down, and its maximum height would indeed just the 300m point it started from.However you’re not starting with the bag stationary. You’re starting with the bag moving upwards at 13 m/s. So the bag is going to start at 300m then move up, come to a halt, then start falling down again. That means the top of its trajectory is above 300m.*

That means the top of its trajectory is above 300m.The 8.6m you’ve calculated is the distance an object moves upwards if it starts with an initial upwards velocity of 13 m/sec. The trajectory of the bag looks like:*
