V = frequency * wavelength
v = 80 * 4
v = 320m/s

Answer:
<h2>4900 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
GPE = 5 × 9.8 × 100
We have the final answer as
<h3>4900 J</h3>
Hope this helps you
