1. Kinematics

2. Equations for Constant Acceleration
x = x0 + v0t + 1/2 at2
v = v0 + at
v2 = v02 + 2a(x-x0)
x = v0t + 1/2 at2
v = at
v2 = v02 + 2a x 10

3. Example: Braking car
A car is traveling 30 m/s and applies its breaks to stop after a distance of 150 m. How fast is the car going after it has traveled ½ the distance (75 meters) ? 18

4. Example: ball thrown up
Vo=25m/s
Find time to go up:
Find max height

5. Example: ball thrown up
Vo=25m/s
Find time to come down:
Find velocity right before it hits ground

6. Example: ball thrown from cliff
Find velocity right before it hits ground
Vo=25m/s
60m
Find total time in air

7. Example: ball thrown from cliff
Find velocity 20m above ground
Vo=25m/s
60m

8. Summary of Concepts Constant Acceleration x = x0 + v0t + 1/2 at2
v = v0 + at
v2 = v02 + 2a(x-x0)
