Sagot :

To find:

The point where the kinetic energy is the greatest.

Explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion. Thus the kinetic energy of an object is proportional to the square of the velocity of the object.

The velocity of the wing will be zero at the extreme points of the path of the swing. But as the swing approaches the mean point, i.e., point 3, the velocity of the swing increases. The velocity will be maximum at the mean point.

Thus the kinetic energy will be the greatest at point 3.

Final answer:

Therefore the correct answer is option C.
