Homework Statement
For a circular orbit around a massive gravitating body, the speed depends on the radius according to Equation 8.3; for elliptical orbits, the speed varies according to the equation v2= 2GM[(1/r)-(1/2a)], where r is the distance from the massive body and a is the semimajor...
Tidal effects in the Earth-Moon system are causing the Moon's orbital period to increase at a current rate of about 35 ms per century. Assuming the Moon's orbit around the Earth is circular, to what rate of change in the Earth-Moon distance does this correspond? Hint: differentiate Kepler's...
Oh, well my physics professor must hate me then. the problem in full is:
State highway 33 south of Stillwater is scheduled for (extensive) modification between the Cimarron river and US 177 by fall 2012. Dr. Hasty has noticed that one of the curves on this asphalt highway (which is scheduled...
So if I am understanding you right, there is a component of mg along the inclined plane downwards which is mg*sinθ and there is a component of centripetal force along the inclined plane upwards which is Fc/cosθ? If that is correct, then I thank you
A car is on a highway curve of 6160 m radius, and the highway is frictionless. The car on a reverse bank angle, aka the the tilt is angled away from the center of curvature. The angle of tilt is 4 degrees. What is the maximum safe speed for cars driving on the highway?
I know that N=...
alright my bad. I am taking the ∫2- 32/16+y2.
first, i separated the parts, so I have ∫2 - ∫(32)/(16+y2).
The first integral is 2y.
For the second integral, i pulled 16 out of the bottom, so i had (32)/((16)(1+(y/4)2)). I canceled out the 32 and 16, so i ended up with (2)/(1+(y/4)2). So then...
Calculate the double integral.
∫∫((5x)/(xsquared)+(ysquared)) dA, R = [1,4] x [0,1].
Find the value of the integral.
Well I tried the integral starting with x and then starting with y and couldn't do it either way. Ill show the method using x first. To start off I tried using...
