Maria and Juan are visiting a water park and decide to travel down different slides, as shown in the diagram. Although the slides are different, they both start and end at the same locations. Maria and Juan start their journey from rest and accelerate down their respective slides. Friction is negligible. Maria has a mass of 50 kg and Juan has a mass of 80 kg.

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?

Determine the time it takes for a satellite to orbit the earth in a circular "near-earth" orbit. the definition of "near-earth" orbit is one which is at a height above the surface of the earth which is small compared to the radius of the earth, so that you may take the acceleration due to gravity as essentially the same as that on the surface. does your result depend on the mass of the satellite?
