# Answer on Mechanics | Relativity Question for Anam

Question #14071

As part of a physics experiment, you stand on a bathroom scale in an elevator. Though your normal weight is 510 N, the scale at the moment reads 640 N. Calculate the magnitude of the elevator's acceleration.

Expert's answer

Let the magnitude of the elevator's acceleration is a.

P = m * g = 510 N

W

= m * (g + a) = 640 N

m = P / g

a = W / m - g = W * g / P - g

a = 640 *

9.81 / 510 - 9.81 = 2.50 N/kg

P = m * g = 510 N

W

= m * (g + a) = 640 N

m = P / g

a = W / m - g = W * g / P - g

a = 640 *

9.81 / 510 - 9.81 = 2.50 N/kg
