Speed, Velocity, and Acceleration
Name: _____________________________________________ Core: _________
Speed and Velocity Problems
Formulas: speed = distance distance = speed x time
time
time = distance velocity = distance (with direction!)
speed time
acceleration = final velocity – starting velocity time = final velocity – starting velocity
time acceleration

2) A kangaroo hops 60 meters to the east in 5 seconds. What is the kangaroo’s average velocity?
3) A turtle crawls for 30 seconds at a speed of 0.75 inches / second. What is the distance the turtle crawled?
4) How much time will it take to travel the 85 miles to Charlotte if we are traveling at an average speed of 65 miles per hour?
5) An ant travels for 60 seconds at a speed of 2 inches per second. What distance did the ant travel?
6) A student rides his bike on a road 5 miles west in 20 minutes. At what velocity did the student ride?
7) How much time will it take to drive 200 miles if we are traveling at an average speed of 70 miles per hour?
8) 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?
9) 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.)
10) A car accelerates at a rate of 3.0 m/s2. If its original speed is 8.0 m/s, how many seconds will it take the car to reach a final speed of 25.0 m/s?
