Chapter 3 (Acceleration Motion) Problems 1. Scooby Doo is moving with an initial velocity of 2.10 m/s. a. If he then has a constant acceleration of 0.220 m/s', what is his velocity after 3.00 seconds? b. How far did he travel in this time? 2. A proton is accelerated uniformly from rest to a speed of 3.50 x 10' m/s. a. If the proton's acceleration was 4.00 x 1012 m/s, how far did it travel while being accelerated? b. How many seconds did it take to attain that final speed in part a? 3. Stewie from "Family Guy" is in a rocket traveling horizontally at 100 m/s. How far does it travel in 5 seconds, if he's moving with constant velocity
