A spaceship moving with an initial velocity of 58.0 meters/second experiences a uniform acceleration and attains a final velocit

Naddika [18.5K]

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
