Can someone plz help me with this I’m not understanding it and show work plz plz

There are two forces acting on the teacher:

Force due to weight/gravity (Fg)

Force due to drag (Fd), which is a resistance opposite to the direction of motion. Think of an airplane flying through the sky: there will be air that tries to oppose the plane's direction of motion AKA air-resistance.

The force of gravity is always downward (the direction of gravity).

Like we said before, the force of drag is always opposite to the direction of motion. Since the teacher is falling down, the force of drag is exerted upward.

Look at the attached diagram. The teacher is the circle in the middle. The two arrows indicate the two forces and their directions.

Now let's look at numbers:

Fg = mg = 65kg * 9.81 m/s^2 = ??N

Fd = 320N

To find the "Net Force" we must add up all of the forces exerted on the teacher, BUT we have to take into account the direction of forces.

Let's define downward as our "positive" direction. Since downward is positive, that means our force due to gravity is positive = +Fg

But since our force due to drag is UPWARD that means our force is NEGATIVE = -Fd.

So our total net force is

An atom that has fewer electrons that protons is called a positive ion.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
