The average person passes out at an acceleration of 7g (that is, seven times the gravitational acceleration on Earth). Suppose a car is designed to accelerate at this rate. How much time (in seconds) would be required for the car to accelerate from rest to 59.9 miles per hour? (The car would need rocket boosters!)
An Olympic runner competing in the marathon finishes with a time of 2 hours, 23 minutes, and 45 seconds. The event has a distance of 26.2 miles. What is the average speed ? average of the runner in kilometers per hour? ?average= ?
As a training exercise, a soccer player must run the length of the soccer field (leg 1), then turn around and run back to her starting point (leg 2) without stopping. If the length of the soccer field is L meters, and she runs the leg 1 in t 1 seconds, then turns around and runs leg 2 in t_2 seconds, find the following: (Write your answers using the symbols as they are written in the question.) a) Her average velocity during leg 1 was L/t'1 m-s 1, b) Her average velocity during leg 2 was L/t 2 m-s1. c) Her average velocity over the entire exercise was m-s 1. d) Her average speed during the entire exercise was 2L/t_1+t_2 m-s1.

You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90 km/h. Is your average speed for the entire trip from A to C 80 km/h? Explain why or why not.
1) A race car travels around a circular race track for which the start line and finish line are at the same location. If the race is 888km long and the radius of the track is 1.414km, how many times did the car go around the track? The race takes 2 hours and 45 minutes, what is the race car’s average velocity (in m/s) over the entire race? What is the race car’s average speed (in m/s) over the entire race?
Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?
A motorist travels 160 km at 80 km/h and 160 km at 100 km/h. What is the average speed of the motorist for this trip? (A) D) 91 km/h B C) 90 km/h E) No answer D A) 84 km/h E) B) 89 km/h
You normally drive on a freeway between San Diego and Los Angeles at an average speed of 105 km/h, and the trip takes 2 h and 20 mins. On a Friday afternoon, however, heavy traffic slows you down and you drive the same distance at an average speed of only 70 km/h. How much longer does the trip take?
Your motion begins at rest and consists of acceleration at 2.0 m/s^2 for 10 seconds, then a period of7.5 seconds with no acceleration, then deceleration at -1.0 m/s^2 for 20 seconds, resulting in a finalspeed of zero. The total distance traveled is 450 m. What is your average speed during this motion? Group of answer choices 10 m/s 42 m/s 12 m/s 16 m/s zero
