Concept:
1. What are the units for acceleration? 2. What is the formula for acceleration? 3. A bullet is shot from a gun, does the acceleration of the bullet change while in flight? 4. Are speed and acceleration the same and why? 5. What do you need to find acceleration?

Rearranging Equation:
1. Solve the acceleration equation for t. 2. Solve the acceleration equation for final velocity.

Calculations:
1. A highway speed chase is going on; rubber is accelerating at a rate of 1.5 km/hr/s. If the initial velocity is 10 km/hr, what is the velocity of the car after 18 sec? 2. What is the final velocity of a fish that takes 15 s to get an acceleration of 1.2 m/s 2. The fish started at a rate of 3.5 m/s. 3. How long does it take a boy to reach an acceleration of 4.00 m/s 2 on his bicycle if his final velocity is 15 m/s after he started from a standstill? 4. A student accelerates at a rate of 4.80 m/s 2 while running. It takes 60 s for her to reach a final velocity of 56 m/s. What is her initial velocity? 5. A cannonball shot into the air achieved a speed of 45 m/s. It had an acceleration of 62 m/s 2, how long did it take to reach its final speed? 6. The plane started at 27 km/hr and slowed to 17 km/hr after 30 s. What was the acceleration of this plane? 7. A hockey puck has a mass of 0.115 kg and is at rest. A hockey player makes a shot exerting a force of 30.0 N on the puck for 0.16 s. With what speed does the puck head toward the goal?
