Answer 3

A i think

Answer 4

@ELB27 do you agree with that?

Answer 5

Yes, definitely A, since potential energy is maximum when speed is 0 and height is max.

Answer 6

Manuel releases a pendulum bob. The drawing shows its path. After the pendulum bob is released, how does the kinetic energy change?



A.
From C to D, it increases.

B.
From C to D, it decreases.

C.
It continues to increase as it swings back and forth.

D.
It does not change.
