All right, that worked for the second problem.
Two to go:
A satellite of mass 730 kg is in circular orbit around the Earth, 3.12x10^6 m above the surface of the Earth. Find the minimum work needed to move the satellite outward and put it in circular orbit at a new height of 6.05x10^6 m above...
So..
- (6.67x10^-11) x (5.97x10^24) x 481 / (9.29 x 10^6 + 6.371 x 10^6) - (- (6.67x10^-11) x (5.97x10^24) x 481 / (6.371 x 10^6) = 1.78E10
is just the change in potential energy.
The change in kinetic energy, 1/2mv^2;
v^2 = GMe/r
Re = 6.371x10^6
v=2pi r/T
Vsurface = 2pi...
Homework Statement
A satellite mass 481 is in circular orbit of 9.29x10^6 m above the surface of the Earth
the weight of a 65.1 kg astronaut inside the satellite
What work was done (ignoring friction) to put the satellite into this orbit. Assume it started at rest on the surface of the Earth...
1. a) A X kg toy car accelerates at constant rate from Vo m/s to Vf m/s in C revolutions while going around a circular track of radius R cm. Find:
- α, the magnitude of the angular acceleration of the car.
- t, the time it took to reach the final speed
2. To calculate the angular...
