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.
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.
You are driving along the street at the speed limit (35kph) and 50 meters before reaching a traffic
light you notice it becoming yellow. You accelerate to make the traffic light within the 3 seconds it
takes for it to turn red. What is your speed as you cross the intersection? Assume that the
acceleration is constant and that there is no air resistance.
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.
A stone is dropped into a deep well and is heard to hit the water 3.41 s after being dropped.
Determine the depth of the well.
A baseball is popped straight up into the air and has a hang-time of 6.25 s. Determine the height to
which the ball rises before it reaches its peak. (Hint: the time to rise to the peak is one-half the total
A tortoise and a hare are in a road race to defend the honor of their breed. The tortoise crawls the
entire 1000 meters at a speed of 0.2 m/s. The rabbit runs the first 200 meters at 2 m/s, stops to take
a nap for 1.3 hours, and awakens to finish the last 800 meters with an average speed of 3 m/s. Who
wins the race and by how much time?
How high can a human throw a ball if he can throw it with initial velocity 90 kph.
With what speed must an object be thrown to reach a height of 91.5 m (equivalent to one football
field)? Assume negligible air resistance.
A 10kg block being held at rest above the ground is released. The block begins to fall under only the
effect of gravity. At the instant that the block is 2.0 meters above the ground, the speed of the block
is 2.5m/sec. The block was initially released at a height of how many meters.
Miguel drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground.
Determine the time required for the shingles to reach the ground.
Brandy throws his mother's crystal vase vertically upwards with an initial velocity of 26.2 m/s.
Determine the height to which the vase will rise above its initial height.
A kangaroo is capable of jumping to a height of 2.62 m. Determine the take-off speed of the
A stone is dropped into a deep well and is heard to hit the water 3.41 s after being dropped.
Determine the depth of the well.
Ronald McDonald is riding an Air Balloon on his way to Subic. If Ronald free-falls for 2.6 second,
what will be his final velocity and how far will he fall?
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 travelled.
A bike accelerates uniformly from rest to a speed of 7.10 m/s over a distance of 35.4 m. Determine
the acceleration of the bike.
An engineer is designing the runway for an airport. Of the planes that will use the airport, the lowest
acceleration rate is likely to be 3 m/s2. The takeoff speed for this plane will be 65 m/s. Assuming
this minimum acceleration, what is the minimum allowed length for the runway?
