Astronauts aboard the U.S.S. Burger decide to fire the rocket thrusters for 3.0 seconds to make a course correction. While the thrusters are on, the ship moves a total distance of 10,500 kilometers and increases its speed by 340 meters per sec. What is the U.S.S. Burger\'s change in speed, in meters per second?

options:

change in speed = 340

change in speed= 1020

Solution

Let initial speed be \'u\' then final sped is \'u+340\'

Change in speed=final speed-initial speed=u+340-u=340

change in speed = 340
