A guy gets into his car at the far end of a parking lot (see figure 1). He turns his car on, revs the engine, and pops the clutch, accelerating at 6.0 m/s2 for 10.0 seconds. At the end of 10.0 seconds he exists the parking lot. How long is the parking lot (distance wise)? Was is its area? Now, another car enters the same parking lot through the same entrance at 10.0 m/s, and then accelerates upon entering at 2.00 m/s2. What is his final velocity as he exists the Parking lot?

READ EVERYTHING CAREFULLY. SHOW ALL YOUR WORK.
1. You are on a different planet, and you have been tasked to determine the acceleration of gravity
on this rather small planet. You climb a top a cliff that is 100.0 m high. You have two balls, and
decided to drop one of them from the edge of this cliff. The ball’s final velocity as it hits the
ground is 20.0 m/s. Calculate the acceleration due to gravity on this planet and the time it takes
for that ball to reach the ground.
You then roll the other ball at 10.0 m/s horizontally off the cliff. How far does this ball travel
horizontally before it hits the ground?
2. Now you are back on Earth. You climb up a top a 100.0 m high cliff and drop a similar ball
from the edge of this cliff. How much time will it take for that ball to reach the ground?
3. A guy gets into his car at the far end of a parking lot (see figure 1). He turns his car on, revs the
engine, and pops the clutch, accelerating at 6.0 m/s² for 10.0 seconds. At the end of 10.0 seconds
he exists the parking lot. How long is the parking lot (distance wise)? Was is its area? Now,
another car enters the same parking lot through the same entrance at 10.0 m/s, and then
accelerates upon entering at 2.00 m/s². What is his final velocity as he exists the parking lot?

4. A cannonball is launched from the ground at 45.0 degrees with an initial velocity of 1.00x10²
m/s. How far does it go horizontally and what is its maximum height? Will this cannonball hit a
target 1019 meters away?
5. An object accelerates from a dead stop; its velocity data is listed in the table below. Calculate
the object's displacement. Then calculate how long it would take a different object to travel the
same displacement if it were to travel at a velocity of 2.50 m/s.
