What is simple harmonic motion?

Simple harmonic motion is a form of periodic motion in which the restoring force on a moving item is proportionate to the amount of the object's displacement.

At the highest point the kinetic energy is equal to the potential energy on the maximum height h;

[tex]\rm mgh = \frac{1}{2} mv^2 \\\\ 2gh=v^2 \\\\\ h= \frac{v^2}{2g} \\\\\ h=\frac{14^2}{2 \times 9.81}\\\\\ h= 9.9 \ m[/tex]

The height at point B is calculated by adding the initial height to the obtained height as;

[tex]\rm h_B = 15+9.9 \\\\ h_B = 29.9 \ m \\\\ h_B=30 \ m[/tex]

The height at point B will be 30 m.

Hence, option D is corect.
