Asolid spherical ball starts from rest at height h at the top of a hill and begins rolling without slipping down the hill.
(a) what is the speed of the ball when it is halfway down the hill?
(b) at the halfway point (height h/2), the hill becomes smooth, so there is no longer any friction between the hill and the sphere. what is the speed of the ball at the bottom of the hill?

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).
