1. Motion Equations

2. Derived Equations Some useful equations can be derived from the definitions of velocity and acceleration

4. An airplane must reach a takeoff speed of at least 27.8 m/s and can accelerate at 2.00 m/s 2. Is a 150 m long runway sufficient to reach this speed? What is the minimum length necessary?

5. How long does it take a car to cross a 30.0 m wide intersection if it accelerates at 2.00 m/s 2 ?

6. A car decelerates at a rate of –6.0 m/s 2. Calculate the total stopping distance for an initial velocity of 100 km/hr.

7. A baseball pitcher throws a fastball with a speed of 44 m/s. Find the average acceleration if the ball moves through a distance of 3.5 m from behind the body to the point of release.

8. How fast must an airbag inflate in order to protect a person traveling at 100 km/hr (60mph)? The bag crumples upon impact a distance of about 1.0 m.

9. Velocity – Time Graphs Distance is the area under a velocity- time graph curve d =(5 x 10) + (1/2 x 5 x10) = 75m
