Question

A satellite moves around the Earth in a circular orbit of radius r. (Use any variable or symbol stated above along with the following as necessary: G for the gravitational constant, ME for the mass of the Earth.) (a) What is the speed vi of the satellite? vi = Correct: Your answer is correct. (b) Suddenly, an explosion breaks the satellite into two pieces, with masses m and 4m. Immediately after the explosion the smaller piece of mass m is stationary with respect to the Earth and falls directly toward the Earth. What is the speed vi of the larger piece immediately after the explosion? v = Incorrect: Your answer is incorrect. (c) Because of the increase in its speed, this larger piece now moves in a new elliptical orbit. Find its distance away from the center of the Earth when it reaches the other end of the ellipse. rf =

Explanation / Answer

the mass of the earth variable. Try M_E instead if you are doing this for webAssign. This can be derived from: G*M_E*m/R^2=m*v_orbit^2/r
