Concept explainers
Whether it is possible for that car with greatest speed crossing the finish line to lose the race.
Answer to Problem 4Q
yes
Explanation of Solution
Introduction:
Speed is scalar quantity whereas velocity is a vector quantity. It is important to mention direction along with the magnitude (speed) for mentioning the speed. The rate of change in velocity is referred as acceleration.
It is possible for that car with greatest speed crossing the finish line to lose the race because the car might not have highest final velocity. The acceleration of other car might be such that it covers large distance in smaller time.
Conclusion:
Thus, itis possible for that car with greatest speed crossing the finish line to lose the race.
