1) A coin is placed 14.5 cm from the axis of a rotating turntable of variable speed. When the speed of the turntable is slowly increased, the coin remains fixed on the turntable until a rate of 40 rpm is reached, at which point the coin slides off. What is the coefficient of static friction between the coin and the turntable?

2) Suppose that a binary star system consists of two stars of equal mass. They are observed to be separated by 340 million kilometers and take 5.0 Earth years to orbit about a point midway between them. What is the mass of each?

______ kg

3) During an Apollo lunar landing mission, the command module continued to orbit the Moon at an altitude of about 90 km. How long did it take to go around the Moon once?

____ min

1) Estimate the following.

(a) how long it took King Kong to fall straight down from the top of a 280 m high building

_____ s

(b) his velocity just before "landing"

_____m/s upward or downward?

2) A helicopter is ascending vertically with a speed of 2.50 m/s. At a height of 110 m above the Earth, a package is dropped from a window. How much time does it take for the package to reach the ground? [Hint: The package's initial speed equals the helicopter's.]

_______ s

3) A baseball pitcher throws a baseball with a speed of 42 m/s. In throwing the baseball, the pitcher accelerates the ball through a displacement of about d = 3.4 m, from behind the body to the point where it is released. Estimate the average acceleration of the ball during the throwing motion.

________ m/s2

4) A stone is thrown vertically upward with a speed of 13.0 m/s from the edge of a cliff 65.0 m high.

(a) How much later does it reach the bottom of the cliff?

_______ s

(b) What is its speed just before hitting?

_______ m/s

(c) What total distance did it travel?

______ m

1) If you are driving 101 km/h along a straight road and you look to the side for 2.0 s, how far do you travel during this inattentive period?_____m

2) A horse canters away from its trainer in a straight line, moving 120 m away in 13.0 s. It then turns abruptly and gallops halfway back in 5.2 s.

(a) Calculate its average speed. ______ m/s

(b) Calculate its average velocity for the entire trip, using "away from the trainer" as the positive direction.______ m/s

3) A car slows down uniformly from a speed of 23.0 m/s to rest in 5.50 s. How far did it travel in that time? _____ m

4) A sports car moving at constant speed travels 110 m in 4.9 s. If it then brakes and comes to a stop in 4.0 s, what is its acceleration? Express the answer in terms of g's, where g = 9.80 m/s2. (Take the positive direction to be the direction of travel.)

_____________g

My great granmother had a stroke two days ago. Her entire right right of the body became paralyzed, she can not talk, ut she struggles to get out of the bed, even though one side of her body cant move. She recognizes pretty much everyone, and when someone asks her something she nods, but she keeps talking(mubling) no one understands,she even gets frustarted when no one understands her. Doctors say she might not get better cuz of age. is there any hope that might get better :(

Various characters comment at certian moments in the film that someone "needs a wake up call" or that "I'm so happy I can't stand it." What do these statements mean? How would you characterize the changes they go through during the film? Do stereotypes and ideals of success in fact restrict youth in exploring their identity and place in society?

The fact that the film was described by some film critics as "degnigrating to Asian American race" begs the qeustion of whether Better Luck Tomorrow claims to represent the Asian American community? who thinks that from the movie, the filmmakers have an obligation to present "their" community only or exclusively in a positive light? what was really the presentation of this film?

+ ten for great answer!!!!!

This article by Catherine Lutz basically explains all the negative outcomes of war and militarization. War means the spending of milllions of our tax dollars and can often have a toll on our economy as well. Along with money also comes the loss of our troops, our family and friends. It is also stated that with war the gap between the rich and the poor becomes more visible and old and new forms of racism emerge in society. Lutz then goes on to talk about militarizism and how it is specified for heterosexual males, to turn them into full blooded men. Militarism may also bring about seperation of social sectors or even create conflict amongst corporations interested in expanding international markets for their goods and then we are the ones who have to suffer the consequences.
