Kepler Problems

1) Mars is 2.278 x 108 km from the sun and takes 687 days to orbit the sun. If Neptune is 4.494 x 109 km from the sun, how long is its year in days? (Use Kepler's third law. Set two equations equal to each other and cancel what you can. You should be left with only T and r to various powers.)

2) The outermost particles in Saturn's rings are 1.35 x 105 km from its center and are moving at 17 km/s. Find the mass of Saturn. (Use Newton's law of gravitation (force) and the radial accelation to find the radial force. Set those equal and solve for mass.)

3) Find the location of the place between the Earth and the moon where the gravitational force on an object of mass m would cancel. (Call the total distance, 3.84 x 105 km D and the distance this place is from the moon x. Write the two force equations and set them equal. Call the mass of the earth me and the mass of the moon mm. The mass of the earth is 5.98 x 1024 kg and the mass of the moon is 7.36 x 1022 kg.)

Friday, Sep 20 - Lab Report Format - For the Force Table lab report, do your sample calculation for the triple vector addition problem. That's the last one on your lab sheet. If you did not do the triple, use the values shown here ( Force Table ) at the bottom of the first page. Draw you force diagram using one of the double force problems you did. DO NOT draw the triple force diagram. Since your results include both magnitude and angle, it is not easy to calculate a % error for the angle. Do the % error for the magnitude but just describe the angle error.
