Respuesta :
A person weighing 823 N is standing on a scale in an elevator is accelerating upward. The scale will read 1159 N.
What is acceleration?
Acceleration is the time rate of change of velocity.
Person weighs 823 N, elevator's acceleration is 4 m/s² and the acceleration due to gravity is 9.8 m/s².
The Net upward force = (823 / 9.8 ) x 4 = 336 N
The force pushing person downward will add up to the weight of person to give the scale reading.
F = 823 N + 336 N
F = 1159 N
Thus, the scale will read 1159 N.
