Abox weighing 200n is pushed on a horizontal floor. what acceleration will result if a horizontal force of 100n is applied on the box. coefficient of sliding friction is 0.4

The acceleration of the block is 0.98 m/s².

Explanation:

It is given that,

Weight of a box, W = 200 N

Horizontal force acting on the box, F = 100 N

Coefficient of sliding friction is 0.4

Net force acting on the box,    

Let a is the acceleration of the box. So,

Since,

So, the acceleration of the block is 0.98 m/s². Hence, this is the required solution.

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
