Question

A man stands on a scale in an elevator that has an upward acceleration

a. The scale reads 928 n. When he picks up a 18.2 kg box, the scale reads 1223 n.

Answer 1

Explanation:

The acceleration is found from ma = m(g + A) = 1226 - 941 = 285 N the augmented weight of the box; so that A = 285/m - 9.8 = 285/22.4 - 9.8 = 2.92 m/s^2

Answer 2

Answer:

w=mg the weight is read in Newtown "n"

Explanation:

so when gravity is multiplied by 18.2kg it gives 1223 n (g=9.8)
