Projectile Motion

Vocab and Stuff

100

This velocity is constant during projectile motion

What is V_x or Horizontal Velocity

200

The horizontal distance that a projectile covers 

What is Range (or x)?

300

This is zero at a projectile's peak. 

What is V_y?

400

Their is a constant acceleration acting on this velocity during projectile motion 

What is V_y or Vertical Velocity?

500

When solving projectile motion problems, it is necessary to break the total velocity into these.

What are components?

Projecting Horizontally

100

When projected horizontally, this is always zero. 

What is V_yi? or a_x works too

200

A plane drops a package, and (ignoring air friction) it lands directly under the plane (as oppposed to infront or behind it).

Why is that?

They both have the same horizontal velocity when launched, and there is no acceleration to change them. 

300

A ball rolls off the edge of a 1.5 m tall counter at a speed of 4 m/s. What is its horizontal range? Round to two decimal places.

2.21 meters

400

A ball is thrown perfectly horizontally from 2m above the ground, and lands 55 m away. What was the balls initial speed? Round to the nearest whole number and include units. 

86 m/s

500

Marvel's newest super hero - "Baseball Man" hits a line drive at 2 x 10⁶ m/s, hitting the ball when it is 5 m above the ground. The center field wall is 5m tall and 200km away. How much has the ball dropped vertically once it has gotten there? Round your answer to the nearest cm

What is 5 cm?

Projecting at an Angle

100

An object is launched at a velocity of 20 m/s in a direction making an angle of 25° upward with the horizontal.

How long does it take to get to the peak?

t_top = .86 seconds. 

200

An object is launched at a velocity of 20 m/s in a direction making an angle of 25° upward with the horizontal.
a) What is the maximum height reached by the object?

What is 3.65 m above the launch point

300

An object is launched at a velocity of 20 m/s in a direction making an angle of 25° upward with the horizontal.

What is its horizontal range?

31.18 m

400

Jordan kicks a soccer ball at an angle of 24° with an initial speed of 15 m/s. If the field he is on is level, how far does it go horizontally before landing?

17.13 meters

500

A ball is kicked upwards at an angle of 45° with an initial speed of 41.58 m/s. Draw a diagram that shows the ball each second with its X and Y velocity vectors (the arrows) for 6 seconds.

Vy should be 29.4, 19.6, 9.8, 0 hen repet. 

Vx should be 29.4 the whole time

Shapes and Stuff

100

A marble is launched at a ten degree angle and an initial velocity of 20 m/s. What is V_x

19.7 m/s

200

A baseball is hit up at an angle of 30 degrees and an initial velocity of 35 m/s. What are the components of the velocity?

Vx = 30.3

Vy = 17.5

300

Matt walks 2 m in a straight line and then another 8m in a straight line. Is it possible that his displacement is 9m?

Yes. 

400

You walk 9m North and the 2m west over the course of 1 minute. Your friend walks the diagonal93 path from your start to your end point. How far do they travel?

9.2 m

500

You walk 90 m south and then 78m east over the course of 2 minutes. Your friend walks along the path of your displacement. How much of a head start can you have and him still beat you if he walks the same speed. 

About 35 seconds. 

Is this Math Class?

100

A ball is dropped from 12 m. How long will it take to hit the ground? 

What is 1.56 seconds

200

A ball is tossed straight up and takes 8 seconds to come to a stop. What was its initial velocity? Round g to 10 m/s²

What is 80 m/s

300

A ball is thrown upward from 12 m above the ground at a speed of 20 m/s. How long will it take to hit the ground (12m below its initial height?)

About 4.58 seconds. 

400

A ball is tossed straight up. 6 seconds later it is falling at 20 m/s. How fast was it tossed up?

What is 50 m/s

500

A marble is rolled such that its Vx = 2.4 m/s and its Vy = 0 m/s. 

10 seconds later what is the displacement of the ball if a_x = 0 and a_y = 2

102.8 m at an angle of 13.4 degrees to the right of vertical.
