4. A bird, accelerating from rest, experiences a displacement of
28 π in 11 π . What is the final velocity after 11 π ?
5. A car decelerates from 100.0 ππ β until it stops in 8.0 π .
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 ππ from a cliff. What is the rockβs displacement after 2.0 π ?
What velocity did it have at the end of this time interval?
