Question

shane is standing still at a bus stop. he is wearing a backpack that weighs 80 newtons.
describe the backpacks motion.
the backpack is __ while experiencing a net force __.
so, the magnitude of the backpacks velocity is ____.

Explanation:

1. Since Shane is standing still, the backpack is not moving relative to the ground; it remains in a state of rest.
2. For an object at rest, the upward normal force from Shane's back balances the downward gravitational force (weight) of the backpack. This means the total sum of forces acting on it is zero.
3. An object at rest has a velocity with a magnitude of 0, as velocity measures the rate of motion.

Answer:

The backpack is at rest while experiencing a net force of 0 newtons.
So, the magnitude of the backpack's velocity is 0 m/s.
