Hi tim, the problem is i don't even know where to start x_X stuck in the begining

The potential energy in space is given as a function of polar coordinates by the following: U(r , therta) = Acos therta / r^2 Given that A = 46 N∙m3, determine the x-component of the corresponding force at the location x = 1.7 m, y = 1.2 m. pls derive a formula to solve this equation

In the middle of empty space two equal masses, M = 2.1 solar masses, lie fixed on a horizontal line separated by a distance D = 8.4 AU. Halfway between the masses lies a third mass. The third mass is displaced vertically a distance y where y << D. Due to the gravitational attraction from the...

One end of a light thin string is attached to a cork with density ρC = 0.24 g/cm3. The other end is attached to a rock. When the arrangement is placed in liquid 1 with density ρ1 = 0.80 g/cm3, a fraction f1 = 0.75 of the cork becomes submerged. When the arrangement is placed in liquid 2 with...
