Question

I NEED HELP!!! PLEASE HELP ME WITH THIS QUESTION PLZZZ!!!!!
The graph below shows the potential and kinetic energy curves for a pendulum. Label each pendulum image with the corresponding letter on the graph (A, B, or C).

Answer 1

Answer:

When ball is thrown straight up from a 10 storey building, its height increases and velocity decreases i.e.potential energy increases and kinetic energy decreases ,then it starts coming down now as the height is decreasing so potential energy also decreases and velocity increases hence the kinetic energy.At some point in downward journey potential and kinetic energy become equal .At this position both graph lines will be at equal height from time axis therefore from graph we can see that its the point C at which both lines are at equal height.
