Question #2

Refer to Figure 1 and state what is being conserved from the moment the ball leaves the launcher( position A) to just after the ball is caught by the pendulum (position B).

1) Both momentum and energy

2) Momentum

3) Energy

Question #3

Refer to Figure 1 and state what is being conserved from the moment the ball and pendulum start to move (position B) until the ball and the pendulum reach their highest point (position C).

1) Both momentum and energy

2) Momentum

3) Energy

Please help me with this homework. Correct me, in case if I am wrong. the question #2 should be both momentum and energy because energy in the ball launcher and lose some energy while launch then momentum is converted collision so that mean when the ball is caught by pendulum? I think Question 3 is also both momentum and energy too? Please let me know soon as possible. I would like to check double, to make sure the answers are correct.

Explanation / Answer

Question2, only momentum, some energy will be lost in form of heat

Question3, only energy, as external gravitational force is acting on the ball

also using 0.5 x (mp+mb)[mbvinitial/(mp+mb)] = (mb+mp)gL(1-cos(theta)) you can find vinitial
