Lizzie is pushing alex on a scooter. lizzie is pushing with 75 n of force to the left, and alex is with 20 n to the left. what is the net force on the scooter?

The net force on the scooter is 95 N to the left.

Explanation:

Lizzie is pushing with 75 N of force to the left, so the force is a vector with 75N of magnitude and to the left.

Alex is helping with 20 N to the left, so the force is a vector with 20 N magnitude and to the left.

When we add vectors, vectors that point in the same direction add up and vectors that point in opposite directions are subtracted.

Hence, the net force is equal to:

F=75 N + 20 N=95 N

As both forces point to the left, the net force is also to the left.

it is called kinetic energy

frequency or wavelenth of em radiation in a vacuum
