    How is potential energy related to orbits of satellites?

    Hi! I really don't even understand what this problem is talking about! If someone could just point me in the right direction, I would appreciate it! A satellite is placed in a noncircular orbit about the Earth. The farthest point of its orbit (apogee ) is 4 Earth radii from the center of...

    What Steps Can Solve the Frictional Force in a Banked Curve Problem?

    The frictional force is the Fsin(theta) for the x/horizontal and Fcos(theta) for the y/vertical. I think I did that part right, but I'm really not that great at physics, so it could be wrong.

    What Steps Can Solve the Frictional Force in a Banked Curve Problem?

    I've been working on this problem for hours and I just can't figure out what to do next! Here it is- A car drives around a curve with radius 410 m at a speed of 32 m/s. The road is banked at 5.0 degrees. The mass of the car is 1400 kg. What is the frictional force on the car? I drew...
