Calculate the man’s height . (Use PE = m × g × h, where g = 9.8 N/kg.)



BRAINLIST TO CORRECT ANSWER



A man climbs a wall and gains a potential energy of 4,620 joules his mass is about 56 what is the height of the wall to nearest tenth of a meter you must show your work (hint) use the formula to do the math

Respuesta :

From the formula PE = mgh, find h.

Divide both sides for mg (because we have them) so we have PE/mg = mgh/mg

h = PE/mg

h = 4620 J/ (56 kg * 9,8 N/kg)

h = 4620 J / 548.8 N = 8.4 m (circa)
