a ballast bag is dropped from a balloon that is 300 m above the ground and rising at a constant velocity of 13m/sec
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?
A ball is dropped from a rocket that is 350 m above the ground and rising at 18 m/s. ( We choose the origin to be at ground level and neglect the air resistance.) (a) What is the maximum height that the ball reached? (b) What are the position and the velocity of the ball after being released for 4s? (c) What is the total time the ball taken to hit the ground?
A coin is dropped from a hot air ballon that is 310 m above the ground + rising vertically at 9.5 m/s. For this problem use a coordinate system in which up is positive. a.) Find the maximum height in meters, that the coin attains. b.) Find the height above the ground, in meters, 4.00 s after being released. c.) Find its velocity, in meters per second, 4.00 s after being released. d.) Find the time, in seconds, that it...
A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is ?0=2.85 m/s . Knowing that at the time of the release the balloon was 60.8 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.
A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is ?0=2.65 m/s . Knowing that at the time of the release the balloon was 84.8 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.
A small bag of sand is released from an ascending hot-air balloon whose constant, upward velocity is vo 2.75 m/s. Knowing that at the time of the release the balloon was 97.3 m above the ground, determine the time τ it takes for the bag to reach the ground from the moment of its release. Use g 9.81 m/s2.
A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is ?0=2.05 m/sv0=2.05 m/s. Knowing that at the time of the release the balloon was 81.8 m81.8 m above the ground, determine the time ?τ it takes for the bag to reach the ground from the moment of its release. Use ?=9.81 m/s2.
Please explain how to solve for these 6. [2 pnts] 52. An object is dropped from a height of 75.0 m above ground level. (a) Determine the distance traveled during the first second. (b) Determine the final velocity at which the object hits the ground. (c) Determine the distance traveled during the last second of motion before hitting the ground. 7. 13 pnts] 57. A coin is dropped from a hot-air balloon that is 300 m above the ground and...
Hot air balloon is rising straight upward at a constant speed of 6.5 m/s. When the basket of the balloon is 20.0m above the ground, a bag of sand falls and reaches a maximum height of 22m. A) Find the speed of the bag before it lands when it is released at 33.0 m. B) Suppose it is descending with a constant speed of 4.2 m/s when the bag of sand comes looose at a height of 35m. What is...
A balloon rises from the ground. When a stone is dropped from balloon at a given instant it takes a time of 2u/g, (u is constant) to reach ground irrespective of position from where it is dropped. Find acceleration of balloon as function of time.
