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.

a ballast bag is dropped from a balloon that is 300 m above the ground and rising at a constant velocity of 13m/sec. For the bag, find..a. the maximum height reachedb. its position and velocity after 5 sec after it was released c. the time it takes to reach the ground
If an object is dropped, the time (in seconds) it takes the object to falls ft is given by the expression Find the time it takes a stone dropped from a height of 324 ft to reach the ground It takes the stone sec to reach the ground
A water balloon is dropped from the top of the Physics building. Assume the balloon does not break when it strikes the ground. a) Create a particular model for this phenomenon by making an energy-system diagram for the process that takes place from the time the water balloon is dropped until it is motionless on the ground. (Hint: consider the indicators to determine what energy systems must be present/can be excluded. Have you included enough systems?) b) If the water balloon is...
A stone is dropped from the upper observation deck of a tower, 200 m above the ground. (Assume g = 9.8 m/s2)(a) Find the distance in meters) of the stone above ground level at time t. (b) How long does it take the stone to reach the ground? (Round your answer to two decimal places.)(c) With what velocity does it strike the ground? (Round your answer to one decimal place.) (d) If the stone is thrown downward with a speed of 8...
A stone is dropped from the upper observation deck of a tower, 400 m above the ground. (Assume g 9.8 m/s2.) (a) Find the distance (in meters) of the stone above ground level at time t (b) How long does it take the stone to reach the ground? (Round your answer to two decimal places.) (c) With what velocity does it strike the ground? (Round your answer to one decimal place.) m/s (d) If the stone is thrown downward with a speed of 5...
A stone is dropped from the upper observation deck of a tower, 150 m above the ground. (Assume g = 9.8 m/s4.) (a) Find the distance (in meters) of the stone above ground level at time t. h(t) = 150 – 4.912 (b) How long does it take the stone to reach the ground? (Round your answer to two decimal places.) 5.53 (c) With what velocity does it strike the ground? (Round your answer to one decimal place.) -54.2 m/s...
2) A little stone is released from an air-balloon that was flying horizontally in the skies. The stone stayed in the air for a period of time of 3 s and hit the ground at an angle of 30° with respect to a vertical line. a) From what height was the rock released from the balloon? b) What was the magnitude of the balloon velocity? c) What was magnitude of the velocity when the rock hit the ground?
2) A...
The height above the ground (in feet) of a stone t sec after it is dropped from a bridge 752 ft above ground is given by the polynomial 752 - 1612 a. Factor the polynomial. b. Use the factored form in part (a) to find the height of the stone 6 sec after it is dropped. a. 752 - 1612-0 b. The stone is ft above the ground 6 sec after it is dropped. Enter your answer in each of...
If the camera is 47m above the ground when it is dropped, how
much time does it take for the camera to reach the ground? What is
the velocity before it lands? Please show/explain ALL work.
A hot-air balloon is descending at a rate of 1.6 m/s when a passenger drops a camera. Part A If the camera is 47 m above the ground when it is dropped, how much time does it take for the camera to reach the...
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...
