(2)<span>less than 750 N.( if the downward acceleration of elevator were g,then answer would be 0 N.)</span>
Simplified gravitational potential energy:
v = mgh
m mass
g gravitational acceleration, on earth = 9.81m/s²
h height
Solve for height.
Measurement tools make our lives safer and better? And they increase the quality and quantity of life. Arguably, the ability to measure calculating
physical properties accurately have tremendous survival value that gives humans adaptive, evolutionary advantages sharpened through many years of natural selection.
