A balloon filled with water is dropped from a height of 20.0 m. At the same time, a dart is fired straight up from the ground below the balloon. The initial speed of the dart is 15.0 m/s.
When does the dart hit the balloon and how high above the ground does the dart hit the balloon?
Assuming that the balloon breaks instantaneously and that the dart doesn’t affect the motion of the water, how long after the balloon breaks does the water reach the ground?

A hot air balloon is rising upward with a constant speed of 20.0 m/s. When the balloon is 20.0 m above the ground, the balloonist accidentally drops a cup over the side. The balloon continue to move up at a constant speed of 20.0 m/s. Ignore the air resistance. (1) What is the distance between the cup and balloon 1 seconds after it is dropped? (2) How long does it take for the cup to reach the maximum height?

a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...

(10 pts) A water balloon is dropped vertically from a height of 44 m above the sidewalk. It lands on the feet of a person who is walking along the sidewalk at a constant velocity When the balloon is released at t 0, the person is i2 m from the point of impact. Ignoring air resistance effects, determine the walking speed of the person. You should calculate that the time to impact is approx. 3 s.]

(10 marks) A small catapult is used to launch 1.5 kg water balloons straight up into the air. A clever student is able to measure the speed of the water balloon while it is rising up into the air. She finds that the water balloon is 8.0 m above the catapult it is moving at a speed of 20.0 m/s. (For the purposes of this question, assume that the catapult is positioned in a small hole so that the height...
