Question

question: the diagram shows a ball hanging on a string. the ball swings from point W to point Z and to point W...(refer the image)
plzz guys it's a request...plzz help me in this question ​

Answer 1

Answer:

a is correct

Explanation:

k.e = mgh

mass is constant , g is constant and h has increased

Answer 2

SoluTion :-

It is a Simple pendulum.

According to conservation of energy ,

$\sf {KE+PE= constant}$

At point Y, PE is minimum.

The kinetic energy at mean position is maximum in this case.

Since, Y is the mean position,

So, the kinetic energy is maximum at point Y.

AnswEr :-

C. The kinetic energy of the ball is maximum at point Y.
