Question
your mass is 50 kg. you stand on a bathroom scale in an elevator on earth.a) what force would the scale exert when the elevator moves up at a constant speed?
b) what force would the scale exert when it slows at 1.8 m/s2 while moving upward?
c) what force would the scale exert when it speeds up at 1.8 m/s2 while moving downward
d) what force would the scale exert when it moves downward at a constant speed?
e) what force would the scale exert when it slows to a stop at a constant magnitude of accerleration?
Explanation / Answer
a) same force = 50 *9.8 = 490 N b) N = m ( g - 1.8) = 50 * 8 = 400 N c) N = m ( g - 1.8 ) = 400 N d) same force = 490 N e) N = m ( g - a )
