Find the orbital speed of a satellite in a circular orbit 1870 km above the surface of the Earth. 1870km = 1.87e6 m I tried using the V^2=GMe/r and came up with 14.6 km/s which is wrong. I tried finding the velocity of earth 7.91 km/s and subtracting from the 14.6 km/s and still the answer is wrong. Am I using th
A woman astronaut weighs 120lb on earth-what does she weigh on mars?
Translate this for me! Fscale-f = Fs Fn = mg f= coefficient of kinetic friction times Fn (normal force) coefficient of kinetic friction = Fs/mg What is meant by Fscale and Fs? These are lab calculations and in the lab I believe "Fscale" was measured by an actual scale used to pull a wooden block but I don't know wha
