A painter is standing on scaffolding that is raised at constant speed. As he travels upward,...
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?
While standing at the edge of the roof of a building, you throw a stone upward with an initial speed of 7.39 m/s. The stone subsequently falls to the ground, which is 16.9 m below the point where the stone leaves your hand. At what speed does the stone impact the ground? How much time is the stone in the air? Ignore air resistance and take g -9.81 m/s. (This is NOT a suggestion to carry out such an experiment!)
Spider-Man launches himself from the ground so that he travels vertically upward, eventually catching hold of a hovering helicopter that is 420 m above the ground. Assume air resistance is negligible as he ascends. (g = 9.8m/s) » What minimum initial takeoff speed must Spider-Man have to reach the helicopter?
Spider-Man launches himself from the ground so that he travels vertically upward, eventually catching hold of a hovering helicopter that is 420 m above the ground. Assume air resistance is negligible as he ascends . ( g = 9 . 8m/s 2 ) What minimum initial takeoff speed must Spider-Man have to reach the helicopter?
While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.43 m/s. The stone subsequently falls to the ground, which is 11.7 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s2 for the acceleration due to gravity. impact speed: m/s How much time is the stone in the air?...
A hot-air balloon is rising upward with a constant speed of 2.85 m/s. When the balloon is 2.80 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground? s
9). A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is ?0=2.75 m/s. Knowing that at the time of the release the balloon was 58.3 m above the ground, determine the time ? it takes for the bag to reach the ground from the moment of its release. Use ?=9.81 m/s2. r= 10) You throw a baseball directly upward at time ?=0 at an initial speed of 14.1 m/s. What is the maximum height...
A hot-air balloon is rising upward with a constant speed of 2.97 m/s. When the balloon is 6.21 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?
A hot-air balloon is rising upward with a constant speed of 2.15 m/s. When the balloon is 2.31 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?
A hot-air balloon is rising upward with a constant speed of 2.65 m/s. When the balloon is 2.80 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?
