The released at A and swings in a vertical arc to points B, C, and D. 2) Refer to the figure above. At what point does the mass have the most potential energy? A) A ?) ? c) c D) D E) none of the given points 3) Refer to the figure above. At what point does the mass have the most kinetic energy? A) A B) B C) C D) D E) none of the given points 4) Refer to the figure above. At what point does the mass have its highest speed? A) A ?) ? C) C D) D E) none of the given points

Explanation / Answer

2) at point A potential energy will be maximum,because height is maximum

3) at point C kinetic energy will be maximum,because at C height is minimum

4) at point C speed will be maximu as kinetic energy is maximum
