Question
what is the right answer. prefer with show work
The pendulum bob in the fig hangs from a cord of length 40 cm. The pendulum bob is pulled about 10 cm to the side (from the equilibrium positon) and gains a height of 1.3 cm. The pendulum is released to swing and the sensor probe "RANGER" measures its horizontal velocity which varies with time as it swings. The maximum kinetic Energy and the maximum potential energy of the pendulum occur at the highest point of the swing. The minimum kinetic Energy and the minimum potential energy of the pendulum occur at the lowest point of the swing. The minimum kinetic Energy and the maximum potential energy of the pendulum occur at the lowest point of the swing. The maximum kinetic Energy and the minimum potential energy of the pendulum occur at the lowest point of the swing.Explanation / Answer
According to the question given,
Correct Answer is : D
Reason : KE is max at the bottom of the pendulum's arc; this is the point at which the pendulum's velocity is at a maximum.
PE is maximum at the top of the pendulum's swing, when it completely stops for a fraction of a second. This is its highest point.
