Superman needs to save Lois from the clutches of Lex Luthor. After flying for 6 seconds, he is 2430 meters
from her. Then at 9 seconds he is 2295 meters from her.
What is Superman's average speed?
meters per second m/s
How far from Lois did Superman start?
meters
Write an equation to model this situation (use d for distance from Lois in meters and s for seconds).
A car moves along a straight road. It moves at a speed of 50 km/hr for 4 minutes, then
during the next 4 minutes it gradually speeds up to 100 km/hr, continues at this speed
for 4 minutes, then takes 4 minutes to gradually slow to a complete stop. Make a
sketch like the figures in Section 1.2 of your textbook, marking dots for the position
along the road every minute.
Superman needs to save Lois from the clutches of Lex Luthor. After flying for 12 seconds, he is 1900 meters from her. Then at 18 seconds he is 1600 meters from her.
What is Superman's average speed?
meters per second m/s

- A tortoise and a hare are competing in a 1200-meter race. The arrogant hare decides to let the tortoise have a 820-meter head start. When the start gun is fired the hare begins running at a constant speed of 8 meters per second and the tortoise begins crawling at a constant speed of 4.5 meters per second. Which of the following formulas expresses the distance between the tortoise and the hare in meters, d, in terms of the number of seconds, t, since the start gun was fired? Od = 820 - 8t Od = 820 + 3.5t Od = 820 - 3.5t Od = 1200 3.5t Od = 1200 - (8t + 4.5t)arrow_forwardYou are stationary and you observe a frisbee being thrown out of a car.

- Answer the following question(s): A student sees her physical science professor approaching on the sidewalk that runs by her dorm. She gets a water balloon and waits. When the professor is 2.0s from being directly under the window about 11m from the sidewalk, she drops the balloon. Finish the story. Instructor Note: There are several ways to reach the correct answer. I generally solve for time to determine if balloon will hit the professor or not based on the given scenario. A formula to use is ?=12??2d=12gt2?d = 1 2 g t 2 where d = distance g = gravitational constant of 9.8 t = timearrow_forwardAnswer parts a, and b of the following question. 7. a) Arthur and Betty start walking toward each other when they are 100 m apart.

- Mario rides his motorcycle in going to school. He drives at an average speed of 30 kilometers per hour. The distance between his house and the school is 15 kilometers. Every time he sees his best friend Jessica walking on the road, he invites her for a ride and lowers his speed. On the other hand, he increases his speed when he wakes up late for school. a) If x represents the time it takes Mario to drive to school with the given distance of 15 kilometers, how will you represent the relationship of his speed (y) versus the time (x)?arrow_forwardQUESTION 2 You start out by driving 72 miles south in 3 hours and 13 minutes, and then you stop and park for a while.
