    Work done on a block on an inclined plane

    1. Homework Statement [/b] A block of weight mg sits on an inclined plane as shown. A force of magnitude F is applied to pull the block up the incline at constant speed. The coefficient of kinetic friction between the plane and the block is Mu. What is the total work done on the block by the...

    Undergrad Calculating Orbital Velocity Ratios for Planets A and B

    Planet A and planet B are in circular orbits around a distant star. Planet A is 8.5 times farther from the star than is planet B. What is the ratio of their speeds Va/Vb This problem seems very simple, thought i could just use F=1/r^2, find the difference in forces, which would also be the...
