Homework Statement
Three identical spherical particles of mass m are each located at the corners of an equilateral triangle with edge length r (each sphere is centered at each corner). Show the magnitude of the net gravitational force on anyone of the particles due to the other two particles...

Okay, here's the question:
A box full of physics books (31 kg) is pushed across the floor at a constant speed by a force of F = 85 N at an angle theta = -40 degrees. Determine the coefficient of kinetic friction between the box and floor.
My question is (for later calculation) if the box...
My professor decided to throw us a curveball to try and solve the following problem:
A third baseman makes a throw to first base 38m away. The ball leaves his hand with a speed of 36m/s at a height of 1.7 meters from the ground and making an angle of 14 degrees with the horizontal.
