100
A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. This is the acceleration of the car.
What is 11.14 m/s/s ?
100
You are on a train going 100 mph (relative to the ground) and see a plane in the air going in the same direction as you. The plane is going 150 mph (relative to the ground). This is how fast a person on the train sees the plane going.
What is 50 mph ?
100
These two vectors remain unchanged in the for the duration of any projectile's flight.
What is the horizontal velocity and acceleration?
100
How do you find the velocity using a position-time graph
What is slope (rise/run)?
100
This is the value for gravitational acceleration on Earth.
What is 9.8m/s^2?
200
Two objects of different masses will fall at the same rate toward earth UNLESS acted on by this force.
What is air resistance?
200
vx and vy are described as ____________ of the vector v.
What are components?
200
A diver running 1.6m/s dives out horizontally from the edge of a vertical cliff and reaches the water 3.0s later. This is the distance away from the cliff they landed.
What is 4.8 m?
200
How do you find average speed.
What is distance/time?
200
This is another term for the parabolic path of a projectile.
What is the trajectory of a projectile?
300
The variable that both the horizontal and vertical motion equations have in common.
What is time?
300
A steel ball rolls with constant velocity on a tabletop 0.950 m high. It rolls off and hits the ground 0.352 m from the edge of the table. This is how fast was the ball rolling.
What is 0.8 m/s?
300
A tiger leaps horizontally from a 12m high rock with a speed of 4.5 m/s. This is how far from the base of the rock will she land.
What is 7.2 m?

300
The linear or angular distance in a given direction between a body or point and a reference position.
What is displacement?
400
A curved line on a position-time or distance-time graph represents this.
What is acceleration?
400
A race car accelerates at a rate of 2 m/s/s uniformly from 18.5 m/s in 2.47 seconds. Determine the distance traveled.
What is 57.9 m?
400
A car traveling at a speed of 50 m/s drives straight off of a cliff. If the cliff is 40 m high, the distance away from the cliff that the car will land is this.

How do you find horizontal velocity?
What is vx=x/t ?
400
This is the distance a projectile lands from its launch point.
