Multiple ChoiceIdentify the choice that best completes the statement or answers the question.
1. Given a velocity time graph for a student skipping, literally skipping to the office to leave early, how would you figure her displacement in the first 30 seconds?a. can’t tell c. areab. y intercept d. slope
2. How far will a car travel in 43.3 seconds if it has a velocity of 18.1 m/s?a. 784 m c. –424 mb. 0.42 m d. 2.4 m
3. A honey bee takes off from rest and accelerates at 10.0 m/s2 for 0.8 seconds. How far does she fly in this time?a. 6.4 m c. 3.2 mb. 8.0 m d. 4.0 m
Short Answer
4. A car starts from rest and reaches 12 m/s after 3 seconds.
What does the word “rest” imply?
5. What base units of mass, length and time are used in the metric system to obtain results in standard derived metric units?
_____
6. A bus driver picks up his bus at the county schools transportation lot, drives his route, bringing 44 excited high school students anticipating a wonderful day of knowledge gathering. He drops them off at school then, completes his elementary school route. He does this again taking them all home in the afternoon and returns the bus to the same parking spot in the county lot. He was gone for 7.3 hours and the odometer reading in the bus increased by 107 miles. His top speed on the trip was 45.0 mph. What was his average velocity?

In a modern version of jousting, two fighter pilots face off with radar guided missiles. They are heading toward each other at the same altitude, 40 km apart when the “good” guy fires his missile. The “bad” guy is having a bad day, he doesn’t even know he’s in a fight and just keeps on flying toward impending doom at 210 m/s. The good guy’s airspeed was 200 m/s when he fired.
The missile’s performance is summarized below. acceleration 75.0 m/s2 top speed 800 m/s engine run time at top speed 25.0 sec Acceleration after motor burn out = –30.0 m/s2
a. The missile will only be able to fly level and maneuver for 54.7 sec. What is the maximum effective range of the missile?
1) How far will it fly while accelerating, and how long will it take to get to top speed?
2) How far will it fly at its max speed, and what time will the motor burn out?
3) How much further will the missile fly before it can’t maneuver anymore?
