This velocity is constant during projectile motion
What is Vx or Horizontal Velocity
When projected horizontally, this is always zero.
What is Vyi? or ax works too
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?
ttop = .86 seconds.
A marble is launched at a ten degree angle and an initial velocity of 20 m/s. What is Vx
19.7 m/s
A ball is dropped from 12 m. How long will it take to hit the ground?
What is 1.56 seconds
James P. Sullivan's nickname in the movie "Monsters, Inc."
What is Sully?
What is Range (or x)?
Why is that?
They both have the same horizontal velocity when launched, and there is no acceleration to change them.
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
Vx = 30.3
Vy = 17.5
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
This is an organism that lives on or in another organism, and causes harm to the host
What is a parasite?
This is zero at a projectile's peak.
What is Vy?
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
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
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.
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.
This US amendment deals with woman's suffrage
What is the 19th amendment?
What is Vy or Vertical Velocity?
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
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
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
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
This is the price to buy a Utility in a standard monopoly game
What is $150
When solving projectile motion problems, it is necessary to break the total velocity into these.
What are components?
What is 5 cm?
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
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.
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 ax = 0 and ay = 2
102.8 m at an angle of 13.4 degrees to the right of vertical.
