Depending on the rubber, what I've found using a porous piece of plywood its around 0.7-0.9

Thank you!

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...
