A skydiver is 780 meters above the ground when he opens his parachute. After opening the parachute, he descends at a constant speed of 20 meters per second. What is a function that would best model this situation?

y = 20x - 780
y= 20x + 780
y =780 + 20x
y = 780 - 20x

Answer:

y = 780 - 20x

CLAIM:

Examine the system model below, which shows a car moving along a track at two different points in time. Assume there is no friction between the car and the track.


In the before image, a car is moving along a track at a constant speed towards a motionless wheel.


In the after image, the car has contacted the wheel, which begins to spin. The car continues to travel along the track at a slower speed.


THE QUESTION:

Which Claim below best explains what causes the wheel to spin after contact with the car?

1 - The wheel stops spinning because kinetic energy was transferred from the car to the wheel.

2 - The wheel begins to spin because kinetic energy was transferred from the car to the wheel.

3 - The wheel pushes the car, causing it to go faster

4 - The wheel begins to spin because kinetic energy was transferred from the wheel to the car.

Guess the song:

I know that you're calling me
To light up and let the shadow
That follows you underneath
I know that you're calling me
I don't wanna play it safe
'Cause I don't get down like that
Just keep falling into me
