- Sarah is driving her car very smoothly from Austin to Dallas one day. At 6:00 pm she is traveling at 20 mph, while 20 minutes later she is traveling at 40 mph. Calculus tells us that at some time between 6:00 pm and and 6:20 pm, her acceleration is exactly x mph. What is the value of x ?How long will it take a boat, moving at 5.6 m/s, to travel 100 meters? a.17.9 seconds. c. 0.056 seconds. b. 100 seconds. d. 560 seconds.I was born in Colorado and 40 years later I live in New Jersey, 1800 miles away. My sister was born in Utah, and 50 years later lives in Idaho, 200 miles away. Who has the lower average speed?
- How far has a car traveled in 4 hours if it is constantly moving at 60 miles / hour? a.60 miles. b.4 miles. c. 64 miles. d. 240 miles.The following conversion equivalents are given:1 mile = 5280 ft 1 ft = 12 in 1 m = 39.37 in 1 hour = 60 min 1 min = 60 sA particle has a velocity of 4.7 miles per hour. The velocity, in m/s, is closest to:A) 2.1 B) 1.7 C) 1.9 D) 2.3 E) 2.5You and Sally are walking to a local restaurant for dinner and disagree about which path would be faster. You each decide to travel on your chosen paths. On your path, the distance to the restaurant is 1.7 miles and you walk at a rate of 4.0 mph. Sally walks at a rate of 4.2 mph and her path is longer at 1.9 miles. Who gets to get the restaurant first? How much earlier does the winner get to the restaurant, in hours or minutes?
- Which of the following primarily moves in a three dimensional reference frame? Question 8 options: a fish in the ocean hockey players on ice an elevator in a hotel a car on level groundYou start out by driving 91 miles north in 4 hours and 10 minutes, and then you stop and park for a while. Finally you drive another 28 miles north in 4 hours and 52 minutes. The average velocity for your entire trip was 10.54 miles per hour to the north. How much time did you spend parked? 4 hours 31 minutes 1 hours 7 minutes 11 hours 17 minutes 2 hours 15 minutesTwo children are walking at the same steady speed of 2 feet/second at the United terminal at O’Hare airport. One steps on the moving walkway and continues walking, while the other continues along the regular floor. The moving walkway moves in the direction of the child’s motion with speed 4 feet/second. The first child stops at the end of the moving walkway and waits 7 seconds for the second child to catch up. How long is the moving walkway (in feet)?
- Playing jackstone as a kid, you discovered that there is a certain time before the rubber ball falls and you took advantage of this when picking up the stars on the floor. If you threw the ball 2.56m/s up into the air, how fast will it be moving at a height of 11.35cm? How much time has elapsed upon reaching this height? Use GRESA and show illustrationYou travel at a constant speed of 6.0 m/s for 2.0 s. If you triple the distance traveled in the same amount of time, what is the speed at which you’re travelling now?Two triggers, 20 feet apart, activate when a car's tires run over them. The time between the two signals is 0.4 seconds. 1) Calculate the speed of the car in mph. (This may speed your conversion: 88 ft/s = 60 mph.) 2) how might someone evade the speed trap, if he spots it just as he's about to hit the first signal?
