Question

A 2550 gram box is pushed across the floor with a net force of 18 .0 N.

What is the acceleration of the box across the floor?

Answer 1

The acceleration of the box across the floor is 7.0588
`m/s^2`

Step-by-step explanation:

Given:

Mass of the box = 2550 gram

net force acting on the box = 18 .0 N.

To Find:

The acceleration of the box across the floor = ?

Solution:

Newton's 2nd Law of Motion states that the acceleration of an object as produced by a net force is "directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. "

Newton's Second Law formula is

F = m a

Where:

F = the magnitude of the net force, in N

m = the mass of the object, in Kilogram

a = the acceleration of the object, in
`m/s^2`

Now substituting the values, we get

18.0 = a (2.55) [since 2550 gram = 2.55 kg]

`a = (18.0)/(2.55)`

a = 7.0588
`m/s^2`
