1. Do Now -Solve and Indicate if the acceleration is positive or negative. Why?  A car is starting its race from the home and increases his speed to 40m/s over the course of the first 5 seconds. What is the race cars acceleration?  A cyclist is driving at a rate of 10m/s and slows his speed to 2 m/s when he sees a large hill. He does this in 2 seconds.. What is the acceleration?

2. Physics Talk  How do you calculate braking distance?  V i 2 =-2ad

3. Physics Talk  How do you calculate braking distance?  V i 2 =-2ad vi2vi2 -2a d
