A circle is located 50.0 m to the west of an island and is moving at 15.0m/s awat from the island when an ocean current arrives. The current gives the crate an acceleration with a magnitude of 3.00 m/s^2, directed to the east you may assume this acceleration remains constant

(a) Set up a coordinate system and establish the initial conditions.
(b) What is the maximum distance from the island the crate reaches? When does this happen? What is its acceleration at this time?
(c) What is its velocity when it returns to its original location? When does this happen? What is its acceleration at this time?
(d) When does it reach the island? What is its velocity at this time? What is its acceleration at this time?
(e) Graph x(t), v(t), and ad!) for the crate on the graphs below. The graphs should have the appropriate axes labels and the values found in (a) -(d). (1) At what time and how fast is the crate moving when it is at three-fourths its maximum distance from the island?

The lights used by mark watley (played by matt damon) during the film the martian seem to be metal halide lamps. metal halide lamps are filled with vaporized mercury and metal-halogen compounds. when an electric current is passed through the lamp, the tube begins to glow a bright white/blue color. if you were to pass this light through a prism to separate the individual light frequencies, you would see a rainbow just as you would if using natural sunlight because of the complexity of the metal halide gas and the vast amount of possible electron transitions. (the study of light in this way is known as spectroscopy and allows astronomers to know exactly what atoms compose distant stars, simply by looking at the light they emit. the spectral lines an atom produces uniquely identifies that atom just like a fingerprint uniquely identifies a person. the momentum equation and energy equation that we have used above can be combined to give the following equation: c = e p where again p is the phonon momentum, e is the photon energy and c is the speed of light. when you divide the photon energy found in #6 by the photon momentum found in #4, do you get the speed of light? (if not, check your work for questions #4 through #6). yes no

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
