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

car a

car b

car c

car d

car e

Car C

Explanation:

It is given that,

Five race cars speed toward the finish line at the Jasper County Speedway. The mass of each car has same mass. The speed of all cars are given as :

Car A = 890 m/s

car B = 850 m/s

Car C = 790 m/s

Car D = 895 m/s

Car E = 870 m/s

The distance is constant because the finish line is same for all cars. The speed of an object is given by the total distance covered divided by total time taken i.e.

Where

d = distance

t = time required by the car to come to a full stop

So, time taken is inversely proportional to the speed of the car. The car having less speed will take maximum time to come to stop. Hence, car C will require longest time to come to a full stop.    

divide the right side by the left side

0.024÷1.2=0.02 for example

as technology advances, new experiments often expose problems in accepted theories. c
