Question

What is the force in units of newtons of a 40 pound object?

Answer 1

Step-by-step explanation:

Given:

Mass of the object =
`40` pound

We have to calculate force (N).

Newton = [kg.ms^-2]=[MLT^-2]

So we have to convert the units.

`1` pound =
`0.45` kg

`40` pound =
`0.45* 40 = 18.14` kg

Here Force and Weight are equivalent as the object is in stationary state.

Weight= product of mass and gravity.

Value of g = 9.8 ms^-2

Force =
`m* g`

So the force of the object in (N) =
`18.4* 9.8`

=
`177.77\ N`

The force in units of Newtons = 177.77
