Question

6.  Tommy and John are trying to move a large table.  John pushes with a force of 1150N and Tommy helps him by pushing on the same side of the table with a force of 800N.  Sketch the individual forces exerted on the table and then calculate and show the net force exerted on the table.

Answer 1

Answer:

Net force = 1150 + 800 = 1950 N

Explanation:

The diagram above illustrate the force applied to the large table by Tommy and John.  The force are exerted in the same direction . The first arrow represent the force applied by John which was 1150 Newton and the second arrow represent the force exerted by Tommy which was 800 newton.  There was no opposing force indicated like gravity from the question so no need to sketch that.

The forces were applied in the same direction, therefore, the Net force can be computed by adding their individual forces .

Net force = 1150 + 800 = 1950 N

Answer 2

First draw a table of sorts. Draw 2 arrows pointing in the same direction towards the table, labeling one as 1150N and one as 800N. Now, since both forces are exerted in the same direction, we can add the forces. So, 1150N + 800N, which is 1950N. There’s no weight and it doesn’t look like gravity is involved. If gravity is involved, just draw an arrow pointed down at the middle of the table, and a normal force pointed up towards the middle of the table. Hope this helps
