Objects that are accelerating.
What is C
An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.
What is 1720 m?
The formula for speed
What is change in distance over change in time?
OR What is the absolute value of velocity?
Object(s) not moving
What are A and E?
Explain if you can or cannot have negative acceleration.
What is yes, if the direction of the vector causes it to be negative
A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110. m. Determine the acceleration of the car.
What is 8.10 m/s2?
Object(s) changing direction
What are B and C
This is the equation you would use if you have acceleration, time and displacement and you wish to find initial velocity.
What is x=vi t + 1/2 at2?
Upton Chuck is riding the Giant Drop at Great America. If Upton free falls for 2.60 seconds, this will be his final velocity.
What is 25.5 m/s
Describes how far something has moved from the origion.
What is Displacement?
This is how you would determine instantaneous velocity.
What is the slope of the tangent line to the curve at that point.
A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled.
What are 11.2 m/s2 and 79.8 m?
Which object(s) show no acceleration?
What are A and E?
A feather is dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s2. Determine the time for the feather to fall to the surface of the moon.
What is 1.29 s?
