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 D.

Explanation:

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.

The answer is car D, which velocity is 895 m/s.

this is poiselle's equation from fluid mechanic in physics. mech eng
