A student places a set of books with a force of 25 n on a lab table with a force of 150 n. What is the normal force pushing upwa
1 answer:
The normal force acting on the legs of the table is 175 N
The weight of the books is the force exerted by the books on the table, and it is given as:
The force exerted by the table is given as:
The parameters above imply that:
- The table and the books are stationary,
- The force exerted by both act in the same downward direction.
So, the normal force acting on the legs of the table is calculated as follows:
Substitute known values
Hence, the normal force acting on the legs of the table is 175 N
