I. The ball has constant acceleration as it moves upward.
II. The ball has constant acceleration at the top of its path.
III. The ball has constant acceleration as it moves downward.
Which would fall with greater acceleration in a vacuum (no air)—a leaf or a stone?
the leaf
the stone
They would accelerate at the same rate.
It is difficult to determine without more information.
Which would fall with greater acceleration in AIR—a leaf or a stone?
the leaf
the stone - less air resistance
They would accelerate at the same rate.
It is difficult to determine without more information.
A car is traveling to the right with a speed of 29m/s when the rider slams on the accelerator to pass another car. The car passes in 110 m with constant acceleration and reaches a speed of 34m/s. We want to find the acceleration of the car as it sped up. What equation should you choose?
v=vo+at
d=vot+1/2at2
v2=vo2+2ad
d=1/2(v+vo)t
Kinematic equation can only be used when you have a constant ....
Position
Velocity
Acceleration
Time
The unit we use to measure acceleration is ___.
m/s
m
s
m/s2
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. Choose the appropriate equation.
v=vo+at
d=vot+1/2at2
v2=vo2+2ad
d=1/2(v+vo)t
Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds, then what is the distance that the sled travels?
Choose the appropriate equation.
v=vo+at
d=vot+1/2at2
v2=vo2+2ad
d=1/2(v+vo)t
If Michael Jordan has a vertical leap of 1.29 m, then what is his takeoff speed if his acceleration is -9.8 m/s2 and his velocity at the top of his leap i 0 m/s?
v=vo+at
d=vot+1/2at2
v2=vo2+2ad
d=1/2(v+vo)t
