04. A 0.095 kg aluminum sphere is dropped from the roof of a 55-m-high building. If 65% of the O. thermal energy produced when it hits the ground is absorbed by the sphere, What is its temperature increase? What is the sphere's original volume? Assume the sphere is solid. What is the sphere's increase in volume? el Vector V is 6.6 units long and points along the negative x axis. Vector /2 is 8.5 units long and points at-55 degrees...

Calorimetry Problem: How to find the percentage of the initial mechanical energy absorbed as thermal energy by the aluminum sphere?
Problem: In a lunar experiment, a 950-g aluminum (920 J/ kg °C) sphere is dropped from the space probe while is 75 m above the Lunar ground. If the sphere’s temperature increased by 0.11 °C when it hits the ground, what percentage of the initial mechanical energy was absorbed as thermal energy by the aluminum sphere? Looking for step by step solution.
A 3.00 kg ball is dropped from the roof of a building 176.4 m high
A 3.00 kg ball is dropped from the roof of a building 176.4 m high. While the ball is falling to Earth, a horizontal wind exerts a constant force of 12.0 N on it. a.)How far from the building does the ball hit the ground? b.)How long does it take to hit the ground? c.)What is its speed when it hits the ground?

A solid sphere has a 0.8 m long string wrapped around it. The free-end of the string is held and the solid sphere is released thus unwinding the string as it falls. Determine how fast the solid sphere will be going at the moment the string is completely unwound assuming no thermal energy is generated. String Blocks & a pulley In the diagram below the red block has a mass of 9 kg, the blue block has a mass of...
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...
