A50-kg student gets in a 1000-kg elevator at rest. as the elevator begins to move, she has an apparent weight of 600 n for the first 3 s. how far has the elevator moved, and in which direction, at the end of 3 s?

The elevator has moved 54 meters upwards.

Explanation:

m= 50kg

F= 600 N

t= 3 sec

a= [F-(m*g)]/m

a= (600N-490N)/50kg

a= 2.2 m/s²

h= (a*t²)/2

h= (2.2m/s²*(3 sec)²)/2

h= 9.9 m

the answer is a. at the equator

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
