Microwave Antennas Its Good A Microwave Antenna With A Mass Of 100kg Sits Atop A Tower That Is 40m Tall. Potential Energy?

(Potential energy = mass g = constant height of 9.8 m / s 2)
= 100 kg (9.8m/s2) (40m)
PE = 39,200 Joules
Value of g = 9.8m/s2 but in another textbook for the calculation 10m/s2 easy use, but note the default value of g is 9.8m/s2
Potential energy = mass * height * gravity constant
Therefore:
PE-antenna = 100 kg * 40 m * 9.81 m / s ^ 2
PE = 39,240 Joules or Joules 39.24Mega --
If a joule = 1 kg m ^ 2 / s ^ 2
Hope this helps
