Five race cars speed toward the finish line at the Jasper County Speedway. The table lists each car’s speed in meters/second. If
each car has the same mass, which car will require the longest time to come to a full stop? Car A Car B Car C Car D Car E
890 m/s 850 m/s 790 m/s 895 m/s 870 m/s
We have: v = d/t From the expression, we conclude speed is indirectly proportional to speed. So, the car which will take longer time must have the smallest speed. Among all the options Car C has the smallest speed. So, it would be your answer.
In short, Your Answer would be Option C) Car C will take longer time than any other.
We know that each car has the same mass, and knowing the velocity of each car, we want to know which car will require the longest time to come to a full stop. Here we may assume that all the cars decelerate at the same rate, so the car with the highest speed is the car that will take the longest income to a full stop.
Scientists have designed solar cells to trap solar energy and convert it to D electrical energy. Its D because converting something has to do with recharging something and electronics have to charge. I hope I helped.
