100
The horizonal velocity of a projectile is independent of this quantity.
What is the vertical velocity?
100
This is the path of a projectile (in the absence of air).
What is a parabola?
200
A physical quantity that has magnitude only.
What is a scalar?
200
In a right triangle, the vertical leg is 15 m/s and the hypotenuse is 20 m/s. This is the trig function would you use to find the angle the hypotenuse makes with the horizontal.
What is sine?
200
This is the result of adding two or more vectors together.
What is the resultant?

A ball is thrown horizaontally at the same time that another ball is dropped from the same height. This ball will the ground first.
What is neither. They will hit at the same time.
200
A ball thrown at this angle will go the farthest.
What is 45 degress.
300
Mass is an example of this type of quantity.
What is a scalar?
300
This trig function is used to find the length of the other leg if values of an angle and a leg are known.
What is tangent?

In the following diagram, which diagram represents the vector addition of C = A + B? (#6PH)
What is II?
300
A ball is thrown from a 100. m cliff with a horizontal velocity of 30.0 m/s. This is the final horizontal velocity of the ball.
What is vx=30.0 m/s
300
At the top of a projectiles path, this is the vertical velocity of the object.
What is 0.0 m/s?
400
Velocity is this type of quantity.
What is a vector?
400
This is used to find the magnitude of the 3rd leg of any right triangle.
What is the pythagorean theorem?
400
Daily Double: Sam walks 10.0 m East and then walks 15.0 m South. Find the magnitude and direction of Sam's displacement. Bonus if you can get the angle correct.
What is 18.0 m South East (Bonus 200 if @ angle of 304 degrees)
400
A cannon shoots a cannonball off a 3500. m cliff at 200. m/s. How long is the cannon in the air? Use g=10.0 m/s^2
What is 26.5 s?
400
A projectile shot with an initial velocity of 51 m/s at an angle of 45 degrees follows a prabolic path and hits a stationary balloon at the top of its trajectory. With what speed does the projectile hit the balloon?
What is 36 m/s? (there is only horizontal speed at the top)
500
Arrows are used to represent this quantity.
What is a vector?
500
In a right triangle, the vertical leg is 15 m/s and the hypotenuse is 20. m/s. This is the angle the hypotenuse makes with the horizontal.
What is 49 degrees?
500
A plane flies north at 230. km/h. At the same time, a wind blows east at 80.0 km/h. You will use this mathematical formula to find the resultant velocity. What is the resultant velocity of the plane and in what direction?
What is pythagorean theorem. 245 km/h NE.
