1. Velocity and Acceleration
Ch. 2 Pg

2. Objectives Use correct SI units to express acceleration.
Describe and analyze motion in one dimension using equations for acceleration.
Understand the relationship between acceleration, displacement, time, and velocity.

3. Motion with Constant Acceleration
Displacement depends on acceleration, initial velocity, and time
Δx = ½ (vi + vf)Δt
Displacement = ½ (initial velocity + final velocity)(time interval)

4. A racing car reaches a speed of 42 m/s
A racing car reaches a speed of 42 m/s. It then begins a uniform negative acceleration, using its parachute and braking system, and comes to rest 5.5 s later. Find how far the car moves while stopping.

5. A car enters the freeway with a speed of 8
A car enters the freeway with a speed of 8.4 m/s and accelerates uniformly for 3200 m in 3.0 min. How fast is the car moving after this time?
