Question

3. The ball becomes embedded in the pendulum after the collision. The ball and the pendulum are now moving at speed v2. The pendulum is still (almost) in its most downward position.

4. The ball+pendulum has swung up to its maximum angle thetamax, where it has slowed to a speed of zero.

From steps 3 to 4 is work or impulse done on the system? What force is responsible for this work/impulse?

Answer 1

Solution:

Ans: Work is done in this problem.

There are two forces responsible for this work, Tension of pendulum string and force of gravity,

Reason:

When ball is embedded in the pendulum,moment is conserved, But after it has embedded the system of ball + pendulum recives a K.E which is then conserved into P.E with the help of forces mentioned above.

I hope you understood the problem and got your answers, If yes rate me!! or else comment for a better solution.
