Equations:
Acceleration = Final velocity - Initial velocity
Time
Time = Final Velocity - Initial Velocity
Acceleration
Problems: In order to receive credit for this worksheet you MUST show your work, formula used,
units, and direction if given. You must also highlight your final answer. You can use a
calculator but you must show all of the steps in the spaces provided. Conversions are written to
the right of the problem.
1. 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?
VI = 4m/s a=? Ve = v + ct
t= 3 sec
Ve = 22m/s
22 mls =4m/sec+ a (3 sec) LAnSoer: a = 6m/sec
Ta-6 m/sec
2. A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration? Is this
acceleration higher than that of a car which accelerates from 0 to 30 m/s in 8 seconds?
3. 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.
4. A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. What is the lizard's average acceleration?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F11a1260a-5083-42fc-b593-ae19dce7e141%2F3d030f03-4a2f-4966-bf10-cb6899d3faec%2Fhxkvcm_processed.jpeg&w=3840&q=75)
