3. Yumyum pulls a box to the left with 300 N of force. Mamu also pulls the box to the left with 250 N of force. The box has a mass of 25 kg.
a. What is the net force acting on the box?
b. What is the box's acceleration?

The net force acting on the box is 550 N (going leftwards) and the box's acceleration is 22 meters per second squared.

Explanation:

A)

The net force acting on the box is the sum of the forces. Since Yumyum pulls with a force of 300 N and Mamu pulls with a force of 250 N, both to the left, the net force (in the x-direction) will be:

B)

The net force is equal to the object's mass multiplied by its acceleration. That is:

Substitute known values:

Find a:

In conclusion, the net force acting on the box is 550 N (going leftwards) and the box's acceleration is 22 meters per second squared.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
