Question

PLEASE HELP ):

An object pulled to the right by two forces has an acceleration of 2.5 m/s2. The free-body diagram shows the forces acting on the object.

What is the weight of the object?

Answer 1

490 N

number 4

Step-by-step explanation:

Answer 2

The first thing we must do for this case is the sum of forces in a horizontal direction.

We have then:

`image`

Substituting values we have:

`image`

From here, we clear the mass of the object:

`image`

We now look for the weight of the object.

`image`

Where,

g: acceleration of gravity (9.8 m/s^2)

Substituting values:

`image`

Answer:

the weight of the object is:

`image`
