What is the SI unit for velocity/speed?
m/s - meters per second
Skylar is doing donuts in the parking lot. Can he have a constant speed and changing velocity? What about a changing speed and constant velocity?
Yes he can have a constant speed and changing velocity, because he can keep his speed constant and his velocity is changing due to his position and direction changing.
No, but he can have a changing speed, because as he does his donuts he can speed up and slow down but he cannot do donuts AND have a constant velocity because his direction is changing constantly.
Can you hum while plugging your nose?

If Alaina is pushing a box to the right with 800 N and Mena is pushing the same box left at 776 N, which way is the box moving and what is the net force?
24 N to the right - WOO GO ALAINA
If Bradley is pushing a car that weighs 1050 kg at a constant velocity of 4 m/s how much force is being applied?
4200 N
What are the SI units for length and mass?
length - meters
mass - grams
Mrs. Barrett got pulled over for “speeding” on her way to Dunkin’. Dunkin’ Donuts in Rantoul is 10.7 miles (17,219 m) from the high school. What was Mrs. Barrett’s average speed if it took her 8 minutes (480 s) to get to Dunkin’? Should she get a citation for speeding based off of her average speed? What drink did Mrs. Barrett get?
speed = 35 m/s or 78 mph
based off her speed yes, but she is cool so its ok.
Iced coffee with caramel and milk and sweet cold foam.
What grade did Mrs Brake teach?
5th grade
A pine cone falls from the top of a pine tree. If the pine cone took 3.5 seconds to hit the ground...
a. how fast was the pine cone traveling when it hit the ground?
b. how tall is the tree?
a. 34.34 m/s
b. 60.1 m
What is the force of a 1000kg elevator free-falling at a constant rate of 9.8m/s2?
9800 N
What is the SI Unit for acceleration?
m/s2 - meters per seconds squared
Mrs. Barrett has gone mad and locked everyone in the classroom. She stacked furniture on the other side of the door and in order to escape you must push through the door with a momentum of 4020 kg m/s. If Hudson weighs 60kg how fast should he go to push through the door? What if Hudson and Alaina, who also weighs 60kg, pushed together? What happened to Hudson's velocity after Alaina joined in?
With Alaina's help they both need to go 33.5 m/s
Hudsons speed would be halved if Alaina helped him push the door open.
What kind of "rocks" does Bob have on display in his classroom this week?
Petrified Wood
A jogger is running from City A to City B at a constant speed. The distance between the two cities is 16 miles. It took the jogger 170 minutes to make the trip.
a. what is the joggers speed in miles per minute?
b.what is the joggers speed in miles per hour?
a. 0.094 miles per minute
b. 5.65 miles per hour

What is SI unit for force?
N - Newtons
Drifting in cars involves a controlled loss of traction in the rear wheels, typically by steering in the opposite direction of the turn, allowing the car to slide sideways. This technique relies on principles of physics, including friction, inertia, and centripetal force. By understanding these forces, drivers can manage the amount of traction lost and maintain control during the drift. When a person is drifting in a car what force causes the car to keep sliding forward while the wheels are turning? In order to encourage sliding, what could you do to your rear tires to decrease friction? What force, of the three listed in the problem, causes the car to move in a circle? (3 points)
Inertia keeps the car moving forward as wheels turn.
Replace back tires with "slick" tires to decrease friction
Centripetal force makes it go round and round

A sled at the top of the hill, when it gets to the bottom it is going at a velocity of 5 mi/hr. It took the sled 3 seconds to get to the bottom of the hill. What is the sled's acceleration in m/s2?
What is 0.747 m/s2
Mr Killion decided to play football with his students. He is all suited up with a helmet and pads and is weighing 81kg with all his equipment. Mr killion starts running towards his students with a velocity of 2 m/s. How much velocity would each student need to push Mr Killion in the opposite direction? HINT: Calculate Mr Killions momentum and use that value to calculate the velocity of each student.
AJ - 61 kg
Hudson - 51 kg
Levi - 58 kg
Who has to run the fastest?
AJ- 2.65 m/s
Hudson - 3.17 m/s
Levi - 2.79 m/s
What is the SI unit for momentum?
kg-m/s2 - kilograms times meters per second squared
Mrs. Barrett kidnaps 3 students and loads them into a jeep with no doors. She greased up the leather seats with Crisco and removed all the seat belts. She is driving like a maniac down 136 toward Rantoul. Right before the sledding hill she takes a SHARP turn left onto CR 700 E without slowing down or braking. What happens to the students in the back seat and why did that happen?
Inertia keeps the students moving forward so when the car turns left they will fly/slide out of the right side of the backseat and tumble down the sledding hill.
How many times does the sun revolve around the earth in one day.
WE revolve around the sun. The sun doesn't revolve around us. So the answer is zero.
