4. A bird, accelerating from rest, experiences a displacement of
28 π‘š in 11 𝑠. What is the final velocity after 11 𝑠?
5. A car decelerates from 100.0 π‘˜π‘š β„Ž until it stops in 8.0 𝑠.
What was its braking distance? What acceleration was needed to stop
vehicle in a given time?
6. A rock is thrown straight down with an initial velocity of
14.5 π‘šπ‘  from a cliff. What is the rock’s displacement after 2.0 𝑠?
What velocity did it have at the end of this time interval?
