Acceleration Worksheet Note: Use the six box method to solve problems 6-9. 1. What does 8 mph/s (miles per hour per second) mean? How would you explain it to someone who doesn’t understand physics? 2. After stopping at a stop sign, Lisa accelerates her motorcycle for 6 seconds at a rate of 8 mph/s. What is her speed after she is done accelerating? 3. Mike is skating down the sidewalk at a speed of 5 m/s when he decides to accelerate for 5 seconds at a rate of 4 m/s/s. What is his speed after he is done accelerating? 4. Sarah is driving down the highway at 50 mph when a deer jumps in front of her car. Sarah accelerates for 2 seconds at -20 mph/s before striking the deer. What is her speed when she hits the deer with her car? 5. A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its average acceleration? 6. A car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. Find the car’s average acceleration. 7. A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. What is the lizard’s average acceleration? 8. If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 50 m/s/s for 3 seconds, what will its final velocity be? 9. Draw a position vs. time graph for a car that is constantly decelerating to a stop. 10. Draw a speed vs. time graph for a car that is constantly decelerating to a stop. 11. Draw a position vs. time graph of a car that is traveling at a constant speed. 12. Draw a speed vs. time graph of a car that is traveling at a constant speed. 13. Draw a picture of motion (using dots) of a moving object that is not accelerating. 14. Draw a picture of motion (using dots) of an object that has positive acceleration. 15. Draw a picture of motion (using dots) of an object that has negative acceleration. Acceleration Worksheet Note: Use the six box method to solve problems 6-9. 1.
