MHT CET Physics question
A simple pendulum consisting of a ball of mass m tied to a spring of length is made to swing on a circular arc of angle in a vertical plane. At the end of this arc, another ball of mass m is placed at rest. The momentum transferred to this ball at rest by the swinging ball is
Answer: (A)
Solution
At the end of the arc (the extreme position) the swinging ball is momentarily at rest, so its velocity and momentum are
