Homework Statement
A 220 lb man stands on a scale in an elevator. What does the scale read when the elevator accelerates upward at 1.6 m/s^2? What does it read when accelerating downward at the same rate
Homework Equations
F=ma, w=mg,
The Attempt at a Solution
m=w/g
220/9.81 = 22.43 ( Mass of the human?)
ma=F
22.43 * (1.6) = 35.88 ( Force of the upward force?)
mg= w
35.88 * 9.81 = 352 lbs ( New wieght?)
