period.
11. Mike’s BMW is travelling at 15 m/s, when it is accelerated uniformly at a rate of 2.5 m/s2 for 6.8s.
What is it’s final velocity?
12. What is the acceleration of Mikes BMW when his velocity decreases from 45 m/s to 10 m/s in 10.0s?
 Challenge. How far does Mike’s BMW travel in this time?
d=vit + ½ at2
13. An engineer must design a runway to accommodate a jet that must reach a gound velocity of 55 m/s
before take off. The jet is capable of an acceleration of 5.5 m/s2.
a. How much time is required for the plane to react takeoff speed?
 Challenge. What must be the minimum length of the runway?
d=vit + ½ at2
