Kinematic Equations Worksheet 1. An Indy-500 race car's velocity increases from 4.00 m/sec to 36.0 m/sec over an interval lasting 4.00 seconds. (a) What is the car's average acceleration? Which kinematics equation did you use to solve this problem? (b) How far does the car travel during this amount of time? Which kinematics equation did you use to solve this problem?

2. A golf ball rolls up a hill towards a putt-putt hole. It leaves the club traveling +2.0 m/sec and experiences an acceleration of - 0.50 m/sec2. (a) What will be its velocity after it has been rolling for three seconds? Which kinematics equation did you use to solve this problem? (b) What will be its velocity after it has been rolling for five seconds? Which kinematics equation did you use to solve this problem? (c) Explain what happened to the ball between three and five seconds. 3. While gliding down a steep hill, a bike rider experiences constant acceleration. After 4.50 seconds, he reaches a final velocity of 7.50 m/sec. The bike's displacement was 19.0 meters. How fast was the bike traveling when it first started down the hill? Which kinematics equation did you use to solve this problem?

4. An airplane starts from rest and accelerates at a constant 3.00 m/sec2 for 30.0 seconds before leaving the ground at the end of the runway. (a) How long was the runway? Which kinematics equation did you use to solve this problem? (b) How fast was the plane moving when it "lifted off" the ground at the end of the runway? Which kinematics equation did you use to solve this problem? 5. An airplane while in flight, accelerates from a velocity of 21.0 m/sec at a constant rate of 3.00 m/sec2 over a total of 535 meters. What is its final cruising velocity? Which kinematics equation did you use to solve this problem?

6. Statistically, a person wearing a shoulder harness can survive a car crash if the acceleration is smaller than - 300. m/sec2. Assuming a constant acceleration, how far could the front end of a car collapse if the car impacts while going 28.0 m/sec and comes to a complete stop?

Which kinematics equation did you use to solve this problem? 7. If a bullet leaves the muzzle of a rifle with a speed of 600. m/sec, and the barrel of the rifle is 0.900 meters long, what is the acceleration of the bullet while in the barrel? [Hint: let the initial velocity reflect the fact that the bullet is at rest in the chamber before the trigger is pulled.]

Which kinematics equation did you use to solve this problem?
