Homework Statement
A satellite with a mass of 5.00 x 10^2kg is in a circular orbit, whose radius is 2r_e, around earth. Then it is moved to a circular orbit with a radius of 3r_e.
a) Determine the satellite's gravitational potential energy from the first orbit to the second orbit.
b)...
Thank you! :)
Bah, I should plugged the numbers back in and checked the statement I made, F_x+F_friction=0. The F_y I solved for does not give me a true statement.
Statements should be as follows then,
F_normal = -(m*-g+Force*sin(theta))
F_normal = (mg-Force*sin(theta))
Therefore...
Homework Statement
In many neighbourhoods, you might see parents pulling youngsters in a four-wheeled wagon. The child and the wagon have a combined mass of 50kg and the adult does 2.2x10^3 J of work pulling the two 60m at a constant speed. The coefficient of friction for the surfaces in...
