Question

A coffee mug sits on a window sill of an apartment window 20 meters off the ground. The cat that lives in the apartment jumps onto the window sill and knocks the mug out of the window, causing the mug to fall toward the ground outside.

1. Before the cat hits the mug, what type of energy does the mug have?

Answer 1

As the mug is falling, what is happening to its energy?
*
1 point

Answer 2

At what position does the coffee mug have the greatest kinetic energy?
*
1 point

Answer 3

4. The coffee mug has a mass of 350 grams. If the cat had also knocked a 2000 gram brick from the window sill, how would the kinetic energy of the brick compare to the kinetic energy of the coffee mug as they both got close to the ground?

Answer 7

Before the cat hits the mug, the mug has potential energy.

Answer 8

As the mug is falling, its potential energy is being converted into kinetic energy.

Answer 9

The coffee mug has the greatest kinetic energy just before it hits the ground.

Answer 10

The kinetic energy of both the brick and the coffee mug just before hitting the ground would be the same (assuming they were dropped from the same height). While the brick has a higher mass, kinetic energy is not directly dependent on mass in this scenario. Both objects are subject to the same gravitational acceleration and fell from the same height, so they would have the same kinetic energy just before hitting the ground.

Answer 11

The cup has the greatest potential energy before it falls, when it is still on the window sill 20 meters above the ground.

Answer 12

I'm sorry but without a visual representation or context, I cannot provide you with answers for this question. For example, if we are referring to a ball being thrown up into the air, then position A (beginning) would be minimum potential energy, and as the ball goes upwards (positions B to E), the potential energy would be increasing, reach a maximum (perhaps at position E), then begins decreasing as it falls down (positions F and G). This is an example and might not apply to your specific question. Please provide more details.

Answer 13

I'm sorry for the confusion, but I still cannot provide accurate answers without a diagram or further context that describes what is happening at each position from A to G. In typical scenarios, such as a ball being thrown and then falling back down, potential energy would increase from the starting point (low position) to the highest position, then decrease as it falls back down. Without specific details, this is the most general answer I can provide. Please provide more details.
