Answer:
Step-by-step explanation:
problem 4
Velocity is +2.0m/s and constant acceleration is -0.5m/s^2
For every second the velocity drop by 0.5 m/s, so after 2 seconds the velocity is 1 m/s.
problem 5
Accelerate from rest to 28m/s means go from 0 to 28m/s so with
a constant acceleration of 5.5 m/s^2 it will take 5.09 second
