A150-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/s^2. determine how much he will weigh (a) on the spring scale and (b) on the beam scale. the acceleration of high-speed aircraft is sometimes expressed in g’s (in multiples of the standard acceleration of gravity). determine the net upward force, in n, that a 90-kg man would experience in an aircraft whose acceleration is 6 g’s.

a)Wt =25.68 lbf

b)Wt = 150 lbf

F= 899.59 N

Explanation:

Given that

m= 150 lbm

a)

Weight on the spring scale(Wt) = m g

We know that

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

If the plane is moving upward with acceleration 6 g's then the for F

F = m a

We know that

a=6 g's

So

F = 90 x 9.99 N

F= 899.59 N

explanation:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
