The weight of an astronaut on Earth surface is 950 N. What is the astronaut weight in a satellite orbiting Earth at an altitude of 500km with a speed of 450 m/s? (g=9.8 m/s2 and REarth = 6400 km). Select one: a. 790 N b. 815 N c. 852 N d. 1020 N

Expert Solution

First, find the acceleration due to gravity at satellite's altitude.

Consider the satellite

Let's assume that the satellite is in a circular path.

The gravitational force experienced by the satellite at altitude is the same as the weight of the satellite

Radius of the orbit = Radius of earth + Altitude

A satellite which has a weight of 35000 N on the surface of the earth is moving in a circular orbit around the earth. The radius of the orbit is 2R where R approx 6,400 km is the radius of the earth. Derive and find the period of the satellite from Newton’s second law. What is the angular momentum of the satellite as it orbits the earth? If we now desire to push the satellite into a higher orbit with a...

An astronaut wants to determine the mass of objects she finds in space. On Earth she chooses a spring and attaches a rock to it that weighs 20 N. After placing the rock on a horizontal table, and attaching the spring horizontally to a fixed point, she stretches the rock 2 cm from equilibrium, in the positive direction. She then releases it from rest. After 30 s has passed, she finds that the rock has gone through 10 cycles and...
