Name: Block: ClassWork: Acceleration What is your definition of acceleration? Define the variables used in acceleration: A= V= t= V0= What is the formula? I Do: Which car should we buy? In 5 seconds, a car moving in a straight line increases its speed from 50 km/h to 65 km/h. What is the acceleration? 1 Diagram 3 Unknown 2 Givens 4 Formula 5 Solve it We Do: In 5 seconds, a truck goes from 0 km/h to 15 km/h in a straight line. What is the acceleration You Do: 1. In 3 seconds, a motorcycle accelerates from 5 m/s to 23 m/s. What is the acceleration? Name: Block: 2. A car starts out at 25 km/hr and speeds up to 50 km/hr in 10 seconds. What is the acceleration? 3. A rocket ship is acceleration from 30,000 m/s all the way to 95,000 m/s. It does so in 500 seconds. What is the acceleration (hint, convert into scientific notations) 4. A frog on a log in the Los Angeles river is drifting along at a leisurely 5 m/s when all of a sudden! She encounters rapids! She accelerates to 20 m/s in 3 seconds. What was her acceleration due to the rapids? 5. The Melbourne shuffle is a dance that incorporates fast heel�toe acceleration. If each step involves starting from rest and speeding up to 3 m/s in .1 seconds, what is the acceleration of a dancer’s foot? 6. Challenge: Braxton is trying to decide if his Lamborghini can accelerate faster than his Ferrari. He knows the Ferrari’s acceleration is 5000 km/hr in 10 seconds. If the Lamborghini can go from a rest to 30 m/s in 6 seconds, does it have a greater or less acceleration than the Ferrari?
