Answer:

1898.94 meters

Step-by-step explanation:

Use kinematics. First, we need to use the equation v(f) = v(i) + at. The final velocity is 19 m/s, the initial velocity is 2 m/s, and the time is 120 seconds (it must be in seconds, so do 3 minutes*60). 19=2+a(180), solve for acceleration.

After solving, the acceleration equals .094 m/s². Next, we need to find the distance, so we will use the kinematics equation v(f)² = v(i)² + 2ad. Final velocity is 19 m/s, initial is 2 m/s, and the acceleration is .094 m/s². 19²=2²+2(.094)(d), solve for distance.

Distance = 1898.94 meters.
