Acceleration Note and Practice
Name: ______________________ _________________is one example of an acceleration this means every _____________ the object goes ___________________________________________________. After ______________ the object is going _________________________ after ______________ the object is going ___________________________ after _____________________ the object is going _____________________. _________________is another example of an acceleration this means every _____________ the object goes ___________________________________________________. After ______________ the object is going _________________________ after ______________ the object is going ___________________________ after _____________________ the object is going _____________________. Calculating Acceleration 1.
A skater increases her velocity from 2.0 m/s to 10.0 m/s in 3.0 seconds. What is the skater’s acceleration? Looking for Acceleration of the skater Solution The acceleration of the skater is 2.7 meters per second per second. Given Beginning speed = 2.0 m/s Final speed = 10.0 m/s Change in time = 3 seconds Formula set up Go to the website ​

Calculate Acceleration. 0 mi/hr 60 mi/hr 0 mi/hr 60 mi/hr 0 mi/hr 60 mi/hr 0 mi/hr 60 mi/hr 1. While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration? (Remember that a negative value indicates a slowing down or deceleration.) Find it: Final speed ______________ Starting Speed ____________ Time to go from starting speed to final speed ___________ Set up the formula and calculate acceleration 2. A parachute on a racing dragster opens and changes the speed of the car from 85 m/s to 45 m/s in a period of 4.5 seconds. What is the acceleration of the dragster? Find it: Final speed ______________ Starting Speed ____________ Time to go from starting speed to final speed ___________ Set up the formula and calculate acceleration 3. A car traveling at a speed of 30.0 m/s encounters an emergency and it takes 3 seconds for the car to come to a complete stop. Find it: Final speed ______________ Starting Speed ____________ Time to go from starting speed to final speed ___________ Set up the formula and calculate acceleration 4. A cart is rolling down a ramp for 5.0 seconds The cart goes from a speed of 55cm/sec to a speed of 90 cm/sec. Find it: Final speed ______________ Starting Speed ____________ Time to go from starting speed to final speed ___________ Set up the formula and calculate acceleration
