Question

A 150-lbm astronaut took his bathroom scale (a spring scale) and a beam scale (compares masses) to the moon where the local gravity is g ! 5.48 ft/s2 . Determine how much he will weigh (a) on the spring scale and (b) on the beam scale.

Answer 1

Answer:

a)Wt =25.68 lbf

b)Wt = 150 lbf

Explanation:

Given that

m= 150 lbm

a)

Weight on the spring scale(Wt) = m g

Wt = 150 x 5.48/32 lbf

Wt =25.68 lbf

(b)

On the beam scale

This is scale which does not affects by gravitational acceleration.So the wight on the beam scale will be 150 lbf.

Wt = 150 lbf
