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:

The corect answer is car D hope this helped (:

Explanation:

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
