A total of 8.0 joules of work is done when a constant horizontal force of 2.0 newtons to the left is used to push a 3.0-kilogram box acrossa counter top. Determine the total horizontal distance the box moves.

Respuesta :

ANSWER

4 meters

EXPLANATION

Given:

• Work = 8.0 J

,

• Force = 2.0 N

,

• Mass of the box = 3.0 kg

Unknown:

• Distance the box moves

Work is the product of the applied force in the direction of motion and the distance an object moves,

[tex]W=F\cdot d[/tex]

In this case, a box is pushed horizontally with a force of 2N producing a work of 8J. Solve the equation above for d,

[tex]d=\frac{W}{N}=\frac{8.0J}{2.0N}=4m[/tex]

Hence, the horizontal distance the box moves is 4 meters.
