Answer:

C. 900J (i tried my best)

Explanation:

the student's mass=60kg

gravitational field strength= 10N/kg:

1kg = 10N

60kg = 600N

(where 600N is the gravitational field strength of the student)

√1.5²+2² (pythagoras theorem)

=2.5m (the stairs' length)

work done= N x distance move in the direction of force (m)

=600N x 2.5m

=1500J @ Nm

1500J - 600N (gravitational field strength of the student)

=900J(??)

-correct me if i'm wrong i'm just a human :)

A person is standing on a spring bathroom scale on the floor of an elevator which is moving up and slowing down at the rate of 2
Alinara [238K]

Answer:

923.44N

Explanation:

Obviously Fn cannot equal Fg since the elevator is moving up  

Where Fn is the force read on the scale

Fg is gravitational force=mg=77.6 x 9.8=760.48N

So we use this equation:  

Fnet = Fn - Fg  

ma = Fn - mg

77.6 x 2.1 = Fn – 760.48

162.96N = Fn – 760.48N  

923.44 N = Fn

The answer is 923.44 N
