Answer:

-0.0426 m

Explanation:

-i / o = h' / h

-1.71 / 0.0237 = 3.04 /o

o = -0.042

1/o + 1/i = 1/f

1/(-0.042) + 1/(3.04) = 1/f

-23.81 +0.329 = 1/f

-23.481 = 1/f

f = -0.0426 m

A 102 kg box is pushed on a linoleum floor with an acceleration of 2.5 ms to the second power. The force of the kinetic movie fr
maria [59]

A force is the push or pull acting on an object as a result of its interaction with another object. Here the net force acting on the box is 297 N

From the question

Given that,  

Mass of the box ,m = 102 kg

Acceleration of the box ,a = 2.5 m/s²

Frictional force acting between the box and the floor ,<em>f =</em> 42 N

Here we have to find the net force acting on the body, F = ?

By Newton's second law of motion,

∑F = ma,

where, F is the net force

m is the mass of the body

a is the acceleration of the moving body

If the body is considered moving in the x-direction then,

F-<em>f = ma</em>

<em>F - 42 = 102 x 2.5</em>

<em>          = 255</em>

<em>F = 255 + 42 = 297 N </em>
