A spaceship moving with an initial velocity of 58.0 meters/second experiences a uniform acceleration and attains a final velocity of 153 meters/second. what distance has the spaceship covered after 12.0 seconds?

Respuesta :

AL2006
The ship's average speed during the 12 seconds is

                         (1/2) (58 + 153)

                     =  (1/2) (211 m/s)

                     =        105.5 m/s .

Traveling for 12 seconds at an average speed of  105.5 m/s ,
the ship covers

               (12 sec) x (105.5 m/s)

           =        1,266 meters  during the acceleration
