While a balloon-supported gondola is rising at a speed of 2.0 m/s, a passenger in the gondola throws a small ball up at a speed of 2.0 m/s relative to his body. A person who measures the ball's velocity at the instant of release will find that the ball's velocity relative to the ground at that instant is 2.0 m/s, up. 2.8 m/s, down. 3.0 m/s, up. 5.0 m/s, up. O 7.0 m/s, up.
A hot-air balloon is rising straight up with a speed of 3.15 m/s. A ballast bag is released from rest relative to the balloon when it is 6.89 m above the ground. How much time elapses before the ballast bag hits the ground?
hot air balloon has just lifted off and is rising at the constant rate of 2.0 m/s. Suddenly, one of the passengers realizes she has left her camera on the ground. A friend picks it up and tosses it straight upward with an initial speed of 11.2 m/s. If the passenger is 2.5 m above her friend when the camera is tossed, how high is she when the camera reaches her? m
A hot-air balloonist, rising vertically with a constant speed of 5.00 m/s, releases a sandbag at the instant the balloon is 60.0 m above the ground. After it is released, the sandbag encounters no appreciable air resistance. a) Find the position and velocity of the sandbag at 0.200 s and 0.800 s after its release. b) How much time does it take for the sandbag to strike the ground after it is released?
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?

49, A hot-air balloon is rising upward with a constant speed of 2.50 m/s. When the balloon is 00 m above the ground, the balloonist accidently drops a compass over the side o the balloon. How much time elapses before the compass hits the ground?
A hot-air balloonist, rising vertically with a constant speed of
5.00 m/s , releases a sandbag at the instant the balloon is 40.0 m
above the ground. (See (Figure 1)) After it is released, the
sandbag encounters no appreciable air drag.
