3. | Amanda has just entered an elevator. The elevator rises and stops at the third floor. Use the particle model to draw a motion
diagram of Amanda during her entire ride on the elevator. Num-
ber the dots in order, starting from zero. (Be sure to consider
how the elevator speeds up and slows down.)

The speed of elevator fast and slows down shows through the diagram.

Explanation:

Given that,

Amanda has just entered an elevator. The elevator rises and  stops at the third floor.

Let us consider the elevator at rest then the speed will be zero.

When elevator start from rest then the speed increases with constant acceleration and near the third floor it slow down with constant deceleration and finally becomes at rest at third floor.

We need to draw the diagram distance and time

Using given data,

First, the displacement A to B will be increases fastly and B to C the displacement increases slowly slowly.

Hence, The speed of elevator fast and slows down shows through the diagram.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
