Question

The kinetic energy of the pendulum bob in figure 15-1 increases the most between locations

A. A and B
B. A and C
C. B and D
D. C and D

Answer 1

Answer:A and C

Step-by-step explanation:

Answer 2

A and C

Step-by-step explanation:

Kinetic energy of a body is given by the expression,
`KE =(1)/(2)mv^2`, where v is the velocity and m is the mass of body.

In case of a simple pendulum the maximum velocity is at it's stationary position.

So maximum velocity i at position C, which means maximum kinetic energy is at position A.

The velocity of pendulum reduces as the angle between vertical stationary and current position increases.

So, velocity at E and A are the minimum, so at A and E the kinetic energy value is minimum.

Now examining the options given, we will understand the kinetic energy increase is maximum in case of A and C.
