the perpendicular component will be = Wy
Wy = w * cos 42.34 = 48.11 N x cos 42.34 = 35.54 N
Answer:
The answer will be 936 N.
Explanation:
Given that
m = 80 kg
Acceleration of the elevator , a= 1.7 m/s² ( upward)
The gravity force on the mass = m g
The reading on the scale = F N
Now by applying the Newton's second law
F - m g = ma
F= m g + m a
F= m ( g +a )
F= 80 ( 10 + 1.7 ) N ( take g= 10 m/s²)
F=80 x 11.7 N
F= 936 N
Therefore the reading on the scale will be 936 N.
The answer will be 936 N.
From what I can see it's D, I did this by simply examining the other answers and seeing that they are beneficial, so, from that information, this one must not be.
