If a tennis ball takes 4.5 sec to reach its peak, how long does it take to reach the other player?
What is 9 s?
what is the range of a projectile?
What is horizontal displacement?
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 launched horizontally 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?
If a person is running at a rate of 5mph North, is this a vector or scalar quantity?
What is vector?
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 displacement of an object that is dropped.
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?
What is 5 m/s at 37o?
This is the equation for horizontal displacement of a projectile.
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?
