A group of college students eager to get to Florida on a spring break drove the 750-mi trip with only minimum stops. They computed their average speed for the trip to be 55.0 mi/h. How many hours did the trip take?
In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life-threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. If we assume that a pilot's speed upon impact was 123 mph (54 m/s), then what was his deceleration? Assume that the trees and snow stopped him over a distance of 3.0 m.

Suppose you take a 3-hour trip in your car. For the first hour, you travel at a speed of 60 mi/hr. The weather suddenly gets very bad so that for the remaining 2 hours you travel at a speed of only 30 mi/hr. What was your average speed for the full three-hour trip? I
Bob rides his bike from point A to B in 2.5hours. The next day Bob increases his average speed by 12.0 km/h and takes 22.5 minutes less time between points A to B. What we know Trip A= 150mins, Trip B=127.5min with an increased ave speed 0.2km/min 1. What was his usual average speed? 2. What was the distance travelled?

A car starts from rest and accelerates at 6 m/s² eastward for 3 seconds, then maintains that velocity for 2 seconds, and then decelerates at the rate of 1 m/s² for 2 seconds. What is the final velocity of the car? Round your answer to the nearest meter per second. Choose positive direction east.
An advertisement for the newest model of a Mercedes sports claims the car can go from 0 to 60 miles per hour (mph) in just 3.3 seconds! a) How many meters per second (m/s) is 60 mph? b) In m/s 2 (sometimes written as m/s/s also, just so you know), what is the supposed acceleration of the sports car? c) Impressed by this claim, Sherry buys one. She hops into her new Mercedes sports car and steps on the gas. She’s an engineer and did the math later on; she discovered that her car’s acceleration is 6.7 m/s2 . i) Is her car’s acceleration faster or slower than the advertisement claims it should be? ii) In seconds, how long did it actually take for Sherry’s car to reach 60 mph
