Solve the all parts of following question given below:
Question: Starting from rest, a truck travels in a straight line for 7.0 s with a uniform acceleration of +2.0 m/s2. The driver then applies the brakes for 2.0 s, causing a uniform acceleration of 2.0 m/s2 over that time.
Part I: What is the truck's speed at the end of the braking period?
m/s
Part II: What is the total distance traveled by the truck (from the point where it started at rest to the end of the braking period)?
m
