Physics
A pendulum is made of a small sphere of mass 0.250 kgkg attached to a lightweight string 1.20 mm in length. As the pendulum swings back and forth, the maximum angle that the string makes with the vertical is 34.0∘∘. Friction can be ignored. At the low point of the sphere's trajectory, what is the kinetic energy of the sphere?
