(10 pts) A water balloon is dropped vertically from a height of 44 m above the sidewalk. It lands on the feet of a person who is walking along the sidewalk at a constant velocity When the balloon is released at t 0, the person is i2 m from the point of impact. Ignoring air resistance effects, determine the walking speed of the person. You should calculate that the time to impact is approx. 3 s.]

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...
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 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
A water balloon is dropped from the top of the Physics building. Assume the balloon does not break when it strikes 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 52.3 kg child slides down a water slide with a velocity of 1.1 m/sec at the top. At the bottom of the slide, she is moving horizontally, y=1.5 meters above the water. She splashes into the water d=2 meters to the left of the bottom of the slide. a: Assuming potential energy to be zero at the water level, what is the mechanical energy of the child at the top of the slide? b: How high is the top...

1. Parachute jumpers land with an average vertical velocity of 5 m/s. With what height of ordinary jump does this compare? 2. A ballast bag filled with sand is dropped from balloon. The observer noted that the bag struck the ground 6 s after its release. If air friction is disregard, how high was the balloon above the ground? 3. A stone is dropped in still air from the deck of a high bridge. The sound of the splash reaches...
