A balloon is moving vertically upward at a constant speed of 10 m/s. When the balloon is at a certain height h above the ground, a stone is thrown horizontally with a velocity of 6 m/s relative to a person at rest in the basket of the balloon. The stone is observed to hit the ground in 5 s. Find h A. 50 m B. 20 m C. 75 m D. 125 m E. 10 m

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?
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.
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...

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...
