Remember to draw a picture to help you think about each problem

1. A person who lives in Los Angeles has a cat who is deathly ill. It must receive a rare medicine as soon as possible. Unfortunately, the medicine it needs is in New York. A Los Angeles train takes off with the cat in it going 152 miles/hour toward New York. At the exact same time, a New York train takes off going 175 miles/hour toward Los Angeles. Los Angeles and New York are 2785 miles away. How long will it take the trains to meet?

2. A new car named the Velandermobilehas been made that goes from 0-60.0 miles/hour in 3.075 seconds. What is its acceleration?

3. A new civil engineer decides to tackle the driving hazard that Lincolnites know as 27th street. They believe that all drivers should be able to go from O street through Capital Parkway without hitting a red light. The two problematic stop lights are the one at Randolph and the one at Capital Parkway. Randolph street is north of Capital Parkway.

a. A car is stopped on O street. There are 7 blocks between O street and Randolph street. If the car's average velocity can be 25 miles/hour south in that region, how long after a car goes south from O street should the light turn green? (8 blocks = 1 mile)

b. There are 3 blocks between Raldolph street and Capital Parkway. If a car's average velocity can be 25 miles/hour south in that region, how long after a car goes south from Randolph should the light turn green?

c. What is the total time it takes a driver to get from O street to Capital Parkway if their average velocity is 25 miles/hour south and they do not hit a red light?

d. If you wanted to accelerate constantly the entire time you drove that stretch, and your average velocity was 25 miles/hour, what would your acceleration be?

e. What would your final velocity be?

4. A water rocket goes from 0 meters off the ground to 2.0 meters off the ground in .046 seconds. What is its acceleration?

5. You are driving on the interstate and decide to pass someone. You go from 75 miles/hour to 85 miles per hour in 5.0 seconds. What is the distance you traveled during this time? (Hint: What was your average velocity?)

6. Draw position vs. time and velocity vs. time graphs for an object at rest, an object traveling at a constant negative velocity, and an object accelerating in a positive direction. There should be 6 total graphs.
