A 500 g mass hangs at the end of a 40 cm long string. It is struck by a 250 g mass moving at 0.5 m/s to the right. They undergo an elastic collision.
a) Find the velocities of both masses immediately after the collision.b) Find the maximum height to which the pendulum rises c) There are two ways to find the angular frequency ω: one from the pendulum equation, and one from the vmax equation. Use both and compare your answers.
