so that at its highest point,

e. This is just twice the time it takes for the ball to reach its maximum height,
.
f. The ball's horizontal position after time
is

so that after the time found in part (f), the ball has traveled

Answer:
Energy is proportional to the square of the amplitude
Explanation:
The energy of a certain wave is defined using its magnitude.
The two quantities are related directly. This means that as the amplitude of the wave increases, its energy increases and vice versa.
Energy is directly proportional to the square of the magnitude of the wave. This means that:
If we have new amplitude = 2 * old amplitude
We will have new energy = (2)² * old energy = 4 * old energy
Hope this helps :)
