from,
d = 1/2gt² - eqn for free falling object
12 = 1/2 * 9.8 * t²
24 = 9.8*t²
t = 1.56 s.
The change in the gravitational potential energy is represented by the equation
u = ΔPE = Δmgh
since the mass of the system will remain constant and the acceleration due to gravity will also remain constant, the equation will become
u = mg Δh

The answer for the following question is answered below.
- <u><em>Therefore the speed of the wave is 0.60 m/s.</em></u>
- <u><em>The option for the following answer is " B".</em></u>
Explanation:
Frequency (f):
The number of the waves that pass a fixed place in a given amount of time is called frequency.
The SI unit of frequency is Hertz (Hz)
Speed (v):
The distance traveled per unit of time is called speed.
The SI unit of speed is m/s.
It is a scalar quantity.
Given:
wavelength of the wave (λ) = 0.10 m
frequency of the wave (f) = 60 Hz
To calculate:
speed of the wave (v)
We know;
According to the equation;
From the formula given below;
<u> v = f × λ</u>
Where;
v = speed of the wave
f = frequency of the wave
λ = wavelength of the wave
From the formula mentioned above;
v = 60 × 0.010
v = 0.60 m/s
<u><em>Therefore the speed of the wave is 0.60 m/s.</em></u>

It really does not help because friction is slowing the players down having to put more energy at what they are doing it would be harder on ice which has about no friction you do not have to put alot of energy doing it
