Answer:

Explanation:

The upward push from the table does not cause the book to rise because it is at equillibrium with the downward gravitational force/ weight of the book which allows it to stay in place and not go up. What is the speed of a 4 kg ball with a momentum of 12 kg *m/s?

Assuming a student pushes a 51.5-kilogram bookshelf across a smooth floor with a net force of 67 N. The approximate acceleration of the bookshelf is:1.3 m/s².

Acceleration

Using this formula

Acceleration=Net force/Mass of bookshelf

Where:

Mass of bookshelf = 51.5 kilogram

Net force = 67 Newton

Let plug in the formula

Acceleration=67/51.5

Acceleration=1.30 m/s²

Inconclusion the approximate acceleration of the bookshelf is:1.3 m/s².
