How do you symbolize the change in height?
What is Dy?
A plane is traveling 300 m/s East and encounters a headwind of 107 m/s West. What is the plane's resulting speed?
What is 193 m/s?
This is the shape of the path of all projectiles.
What is parabolic?
What is the initial vertical velocity of a horizontal projectile?
What is 0?
If a tennis ball takes 4.5 sec to reach its peak, how long does it take to reach the other player?
What is 4.5 s?
How do you symbolize the range of a projectile?
What is Dx?
Sally is rowing down a river at 7 m/s North and encounters a current that is 10 m/s North. What is her resulting speed?
What is 17 m/s?
It doesn't change, this velocity stays the same.
What is horizontal velocity?
What is the acceleration of this type of projectile?
What is 10 m/s^2?
The initial horizontal velocity (vi in the x-direction) for a ball thrown horizontally off a cliff is 40 m/s. The ball stays in the air for 3 seconds. How far from the base of the cliff does it land?
What is 120 m?
This velocity is constant throughout the projectile's path.
What is horizontal velocity?
John walks North 8 m, West 1 m, and South 8 m. What is his resulting displacement?
What is 1 m W?
This is the only force that acts on a projectile.
What is gravity?
How does the initial speed of an object effect the time the object spends in the air and how far the object moves?
What is no effect on time, but will go farther?
A soccer ball is kicked horizontally off a 22.0-meter high hill and lands a distance of 35.0 meters from the edge of the hill. Determine the initial horizontal velocity of the soccer ball.
What is 16.7 m/s?
A bird boat is traveling 10 m/s North and encountered a current that is 3.5 m/s North. What is its resultant velocity?
What is 13.5 m/s?
This is the equation for vertical components.
What is Dy=1/2gt^2?
For a ball that’s shot at an angle, explain what happens to the acceleration throughout the flight.
What is Acceleration remains the same?
A physics student who is curious about the trajectory of a paint ball stands with his gun horizontally and fires it off. The paint ball leaves the gun from a height of .75 m and lands on the ground 3.0 m away. What was the horizontal velocity?
What is 7.7 m/s?
Displacement refers to how far out of place an object is and it is the object's overall change in position. Is displacement a vector or scalar quantity?
What is vector?
John walks in a straight line from point A to point B. Mary also walks from point A to point B, but chooses a curved path that causes her distance to be 10 m more than John's. True or false, May and John's displacement is the same?
What is true?
This is the equation for horizontal components.
What is Dx= Vx*t?
A baseball is thrown horizontally off of a cliff with an initial velocity of 80 m/s. A bowling ball is dropped from the same cliff at the same time. Which hits the ground first?
What is both?
A rock is kicked horizontally off a building with an initial velocity of 40 m/s. The rock falls for 5 seconds. Determine the height of the building.
What is 123 m?
