Question

potential to kinetic energy ... shows the ramp gravitational potential energy is transformed into kinetic energy. part b consider this second situation involving the transformation of potential energy to kinetic energy. graph c represents what point in the pendulum’s swing? a point 1 b point 3 c point 5 d at no point in the swing

Explanation:

In a pendulum's swing, at the lowest point (Point 3, the equilibrium position), potential energy (PE) is minimum and kinetic energy (KE) is maximum. Graph C shows high kinetic energy and low (or zero) potential energy, which matches Point 3. Points 1 and 5 are the highest points (maximum PE, minimum KE), so they don't match Graph C.

Answer:

B. Point 3
