Question

On the Moon, Jim had a weight of 27.5 lbf (27.5 pounds-force).

Answer 1

Answer:

Jim had a weigh 165 lbf on Earth.

Step-by-step explanation:

Weight:

The product of mass and acceleration due to gravity.

weight= mass× g

Mass: The amount of material in an object is known as mass of the object.

Mass does not depends on g. Mass of an object remains same.

Given that,

Jim had a weight of 27.5 lbf on the moon.

So,

$mg_m=27 \ lbf$ .......(1)

m = mass of Jim

$g_m$= acceleration due to gravity on the moon.

Again,

The value of force of gravity on the Moon is one sixth of that on Earth.

$g_m=\frac16 g$

g =  force of gravity on Earth.

Now plug $g_m=\frac16 g$ in equation (1)

$m\times\frac16 g =27 \ lbf$

$\Rightarrow mg=(27\times 6) \ lbf$

⇒mg = 165 lbf

Jim had a weigh 165 lbf on Earth.
