Final Jeopardy
$300 -- Vector Components
If I have VX and VY, how I find the angle θ thatV makes with the horizontal.
$200 -- Equations
The equation for finding V0Y if you don’t knowthe angle θ (i.e. V0Y in terms of g and total time of flight) .
$200 -- Concepts
This is the mathematical name for the shapeof the trajectory of an object undergoingprojectile motion.
$400 -- Concepts
It is the length of time for a projectileto reach the apex of its trajectory if thetotal time of flight is T seconds.
$500 -- Concepts
If a projectile lands at the same height from which it was fired, this is the speed with whichit hits the ground if its initial speed was V0.
$100 -- Calculations
If a projectile is fired at an angle of 300 andat an initial speed of 22 m/s, this is the lengthof time it will take to go 45 m horizontally.
$200 -- Calculations
If a projectile is fired at an angle of 400 andat an initial speed of 20 m/s, this is the lengthof time it will take to reach the apex of itstrajectory.
$300 -- Calculations
If a ball is thrown horizontally with a speed of25 m/s off a 120m cliff, this is how long it will take for the ball to hit the ground.
$400 -- Calculations
If a ball is thrown horizontally with a speed of25 m/s off a 120m cliff, this is how far from the edge of the cliff it travels before it hits the ground.
$500 -- Calculations
A plane flying horizontally at a speed of 200 m/s drops a care package from a height of 1000m. Whenthe care package hits the ground, these are the magnitude and direction (measured from the positiveX-axis) of its final velocity.
$100 – Pretty Pictures
If the V0 vectors in these three graphs are the sameMagnitude, this graph corresponds to a trajectoryWith the highest max height.
$200 -- Pretty Pictures
If the V0 vectors in these three graphs are the sameMagnitude, this graph corresponds to a trajectoryWith the maximum range.
$300 -- Pretty Pictures
If the V0 vectors in these three graphs are the sameMagnitude, this graph corresponds to a trajectoryWith the lowest max height.
$400 – Pretty Pictures
If the V0 vectors in these three graphs are the sameMagnitude, this graph corresponds to a trajectoryWith largest V0X.
$500 -- Pretty Pictures
If the V0 vectors in these three graphs are the sameMagnitude, this graph corresponds to a trajectoryWith largest V0Y.
Final Jeopardy
Jessica paddles at 3 m/s due West and a current carries her 4 m/s to the North, so this is the magnitude of the vector that describes her velocity.
