Apiano is suspended 3.6 m above the ground and is being raised to an apartment 50m high with a constant speed of 0.62m/s. after the piano has been moving upward for 3.5 s a coffee cup falls from the apartment window onto the piano. at what height above the ground is the piano when the cup strikes it?

The piano is at a height of 5.8 m from the ground when the cup strikes it.

The piano travels with a constant speed v of 0.62 m/s for a time t of 3.5 s. The distance d traveled by the piano during this time is given by,

The piano is at a height of 3.6 m from the ground, before it ascends with a constant speed.

Therefore, the height h of the piano from the ground is given by,

The height of the piano from the ground is 5.8 m.

d) physical means can be used to separate the components of air.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
