1. Velocity and Acceleration
Ch. 2 Pg

2. Objectives
Describe and analyze motion in one dimension using equations for acceleration.
Understand the relationship between acceleration, displacement, time, and velocity.

3. Velocity with Uniform Acceleration
vf = vi + aΔt

4. Example:
A plane starting at rest at one end of a runway undergoes a uniform acceleration of 4.8 m/s2 for 15 s before takeoff. What is the plane’s speed at takeoff?

6. Displacement with Uniform Acceleration
Δx = viΔt + ½ aΔt2

7. Example
How long must the runway be for the plane to takeoff?

8. A car with an initial speed of 31
A car with an initial speed of 31.4 km/h accelerates at a uniform rate of 1.2 m/s2 for 1.3 s. What is the final speed of the car? What is the displacement of the car?
