Concept:
1. What is the equation for acceleration? 2. What are the units for acceleration? 3. How are velocity and acceleration related? 4. What does final velocity mean? 5. What does initial velocity mean?

Rearranging Equation:
1. How would you find v i using the acceleration formula? 2. Rearrange the acceleration equation to find final velocity.

Calculations:
1. What is the acceleration of a car that starts at 0 m/s and reaches a top speed of 50 m/s in 2 sec? 2. A baseball is thrown by a pitcher at 90mph and reaches the plate in .75 s. What is the acceleration of the ball? 3. How long would it take a teen to reach an acceleration of 5.00 m/s 2 on his skateboard if his final velocity is 14 m/s and he started from a standstill. 4. What is the final velocity if a shark took 50 sec with an acceleration of 1.9 m/s 2 chasing a fish starting at a rate of 1.0 m/s? 5. A bus is accelerating at the rate of 25km/hr/s. If the initial velocity is 20 km/hr, what is the velocity after 20sec? 6. What is the final velocity of a wheel that has an acceleration of 5.2 m/s 2. The wheel started at 3 m/s and rolled for 4 sec? 7. A rocket flies at a speed of 500 m/s after 15 s, what is its acceleration?
