Aworker with spikes on his shoes applies a constant horizontal force of 20 n to push a 40-kg box across a frictionless, frozen lake. what is the acceleration of the box?
2.0 m/s^2
0.5 m/s^2
4.1 m/s^2
8.0 m/s^2

The acceleration of the box will be

Explanation:

Given:

Constant horizontal force on the box= 20 N

Mass of the box=40kg

To Find:

Acceleration of the box=?

Solution:

According to Newton's Second  Law,

Force = Mass x Acceleration

On substituting the values,

Solving the equation for Acceleration

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
