Can someone tell me what I'm doing wrong here?
When you weigh yourself on good old terra firma (solid ground), your weight is 126 lb. In an elevator your apparent weight is 118 lb. What are the direction and magnitude of the elevator's acceleration?
I have Wa = W-ma = mg-ma
Wa=118lb
m=126lb
g=-9.8m/s
So I have 118 = (126)(-9.8) - (126)a and solved for a but I'm not getting the right answer. I wasn't sure if the 9.8 should be negative or not but I tried both and neither is working. Any help would be appreciated
