Question 1 A car has an initial velocity of 234 miles per hour and slams on its breaks, stopping in 4 seconds over a distance of 17 meters. In terms of physics, what is the biggest problem with this sentence? velocity should be in meters per second, not miles per hour A car travelling at that speed cannot stop in 4 seconds Cars don't travel at 234 miles per hour, so the problem is nonsense The word "brakes" is misspelled as "breaks" Question 2 A bowling ball is dropped from the top of a building. It takes 13 seconds for it to strike the pavement below. At the moment it strikes the pavement, the bowling ball is traveling at 127 meters per second. The value of 127 / 13 is equal to: The acceleration from gravity The acceleration from air friction total displacement final velocity Question 3 A plane flies in a straight line at a constant speed of 15m/s for 4 hours. Which variables CAN be deduced from this information? velocity and time velocity, displacement, acceleration and time velocity and acceleration velocity, displacement and time Question 4 An archaeologist is climbing up a steep canyon wall. The total height of the canyon is 100m. As the archaeologist climbs, he starts to get tired. His climbing slows by .01m/s for every second he spends climbing. This value is his; acceleration deceleration velocity speed Question 5 A runaway railroad car hits a pile of sand on the tracks. The car plows through 5 meters of sand before coming to a stop. Which variables CANNOT be deduced from this information? Final velocity, acceleration and time Starting velocity, acceleration and time Displacement, acceleration and starting velocity Displacement, time and starting velocity Join eNotes to save your quiz results!
