15. If an object accelerates from rest, with a constant acceleration of 5.4 m/s2, what will its velocity be after 28 s?
16. An object is traveling at a constant velocity of 15 m/s when it experiences a constant acceleration of 3.5 m/s2 for a time of 11 s. What will its velocity be after that acceleration?
17. An object is moving at a velocity of 23 m/s. It accelerates to a velocity of 85 m/s over a time of 8.3 s. What acceleration did it experience?
