Hey! I see you found my physics tests page. All these tests are 1st semester only! the next page is 2nd semester, I do in fact have the semester final in December. However the only difference from these tests and the ones you'll be taking in regular Physics next year is that the numbers will be different (that is all). I also would put the answers with the questions but i didn't do too well on any of the tests, but i did get some answers sooo... if you need an answer to some question I just might have it (e-mail me the question, and the test number) so! enjoy!

Ch. 1 Test 1
Instructions:
1. You may use one 8 1/2" x 11" page of your own notes (turn in with test)
2. One calculator per student (no sharing)
3. Show all work below each question as is applicable (no work will result in a loss of points)
4. Show proper units in both your work & answers.
5. Place answer in the space provided.
6. Be neat!
Tom takes a very short trip in his new car. First he backs up at 4 m/s for 40m. Next, Tom drives foreword for 15s at 6 m/s. Assuming that foreword is the postive direction & that Tom drives at a constant speed as he backs up at 4 m/s & as he drives foreword at 6 m/s...
1) How long (time) did Tom spend backing up?
2) How far (distance) did Tom travel as he drove foreword during the last part of his trip?
3) What was Tom's average speed for the whole trip?
4) What was Tom's average velocity for the whole trip?

Ch. 1 Test 2
Bob and Ann are going to run a 100m race. Since Ann is faster than Bob she gives him a 10m head start. Bob runs the race (the "last" 90m) at a constant speed of 6 m/s. Ann runs the 100m race (at a constant speed) in 12s.
1) How long (time) did it take Bob to complete the race?
2) How fast (speed) did Ann run the race?
3) Using 1 km = .6 miles & 1,000m = 1 km (as well as appropriate time conversions) convert Bob's speed into miles/hour.
4) At what point (displacement) did Ann pass Bob? If you answer this question by plotting both runners travels (the race) on a displacement -vs- time graph then be sure to attach you completed graph.

Ch. 2 Test 1
A car traveling at 15 m/s needs to pass a truck. As the car passes the truck it spends 10s uniformly accelerating up to a speed of 20 m/s.
1) At what rate is this car accelerating at as it passes the truck?
2) How far did the car travel as it passed the truck?
3) What was the car's average speed during the 10s it spend passing the truck?
The same car as above must slow down due to traffic immediatly after passing the truck. The car does this by decelerating at 1m/s^2 for 15s.
4) How far did the car travel as it was slowing down? (Reminder: The car was traveling at 20 m/s just before it started slowing down.)
5) What was the car's average speed for the whole 25s? (passing the truck & slowing down due to traffic)

Ch. 2 Test 2
In a 100m drag race between car A & car B both cars start from rest. During the race car A uniformly accelerates at 8 m/s^2 while car B uniformly accelerates at only 7.6 m/s^2.
1) How long (time) did it take car A to finish the race?
2) How far behind (distance) was car B when car A finished the race?
3) If the driver of car A wanted the race to end in a "tie" how long (time) would she have to wait after the race started before she actually started to accelerate?
A cop cruising at 20 m/s is passed by a speeder moving at a constant 24 m/s. As the cop is being passed he starts to accelerate after the speeder at .5 m/s^2.
4) How long (time) will it take the cop to catch/pass the speeder?

A bird flying at 10 m/s due North gets caught in a cross wind that is blowing due East. As a result of this cross wind the bird is blown off course in a [N 36.87°E] direction.
5) What is the speed of this cross wind?
6) In what direction should this bird change his heading to so that he actually does fly due North relative to the ground?
A jet has an air speed of 100 m/s & a heading of [N 60°W]. This jet is caught by a cross wind that is blowing at 75 m/s in a [N 30°E] direction.
