What is the formula for acceleration?
(Vf - Vi)/ time

Why you must you arc a football if you want to throw it a greater distance?
Because once the football is released it becomes a projectile and is under the force of gravity.
300
Is it possible for two object to have the same speed but different Velocities?
Yes, they could both be going the same speed but one of the objects could be traveling north while the other object could be traveling south.
300
Is it possible for object to have the same velocity and different momentums?
Yes because one could weigh much more or much less than the other object.
300
What are the three ways acceleration can change?
Speeding up, speeding down, changing direction.

If a cannonball is fired 50 meters west and takes 5 seconds to travel that distance, what is the velocity of the cannonball?
50m/5seconds = 10meters/seconds West
400
Is it possible for objects to have the same mass and different momentums?
Yes because one could have a much greater or lesser velocity than the other.

What is Centripetal Acceleration? Why is it relevant to you every single moment of every single day.
Acceleration toward the center of a curbed or circular path.
Earth revolving around the Sun.

Sophia has a momentum of 1500(kg)(m/s) South. If sophia had a mass of 50kilograms, what would be her Velocity?
30m/s South
500
An object is moving at 45m/s North and travels for 15 seconds. How many meters did the object travel?
675meters North
500
A cannonball traveled 150 meters in five seconds, weighed 50kilograms, and was fired towards the south. What would be the momentum of the cannonball?
150meters/5seconds = a velocity of 30m/s South
50kg x 30m/s South = 1500(kg)(m/s) South.

A skateboarder has an initial velocity of 3m/s West and comes to a complete stop in 2 seconds. What is the skateboarder's acceleration?
(0m/s west - 3m/s west) / 2 seconds = -1.5m/s2 West

1000 point question
Tamara pulls out of her driveway and increases her speed to 15 meters/second in 5 seconds. She then drives straight for 10 seconds. She then slows down to a complete stop over the course of 3 seconds because her car engine breaks down.
