A sports car is accelerating up a hill that rises 22.0° above the horizontal. The coefficient of static friction between the wheels and the road is µs = 0.88. It is the static frictional force that propels the car forward.

a) What is the magnitude of the maximum acceleration that the car can have?

b) What is the magnitude of the maximum acceleration if the car is being driven down the hill?

A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 23.0° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 52.0 kg, and the coefficient of kinetic friction between the skis and the snow is 0.190. Find the magnitude of the force that the tow bar exerts on the skier.

In a TV set, an electron beam moves with horizontal velocity of 3.4x10^7 m/s across the cathode ray tube and strikes the screen, 45 cm away. The acceleration of gravity is 9.8 m/s^2 .
How far does the electron beam fall while traversing this distance? Answer in units of m.

Any help appreciated thanks.

At a given instant, the total acceleration of a particle moving clockwise in a circle of radius 2.05 m. The magnitude of the total acceleration of the particle at the given instant is 14.8 m/s^2; the angle between the vector of total acceleration and the radius-vector of the particle is 30 degrees. At this instant of time, find the centripetal acceleration of the particle. Answer in units of m/s2.

2.Find the speed of the particle at the samemoment. Answer in units of m/s.

3.Find particle's tangential acceleration at the same moment. Answer in units of m/s^2.

Can someone do this problem and tell me what u get for the answer. I have all the formulas but for some reason i keep getting the wrong answer.

My daughter came home with a question that I have no idea how to help her with. Her math teacher asked the class to work out:

A farmer has 10 sows. Each sow had 14 piglets, 7 of which were sows. How many pigs will he have in 5 years? Indicating working out would be greatly appreciated. I assume each sow gives birth to 7 sows and 7 hogs.

If the definition of plagiarizing is "to take and use ideas, passages, etc. from (another's work) by plagiarism", then just HOW am I suppose to answer my professor's question to "discuss the western landscape" in Death Comes for the Archbishop? All the ideas on how and why the landscape is used have been used time and time again by many students, critical reviers, and more! *sigh* I'm so stuck here. I can re-hash their ideas in "my own words" but the "ideas" are the same!
