The Four Uniform<br />
Acceleration<br />
Equations<br />
Quick Check<br />
Four equations describing uniform acceleration were introduced above. These four<br />
equations are extremely useful in this course and in future courses you might take in<br />
physics. For your convenience, they are summarized here:<br />
(1) v f = v 0 + at<br />
(2) d = v0 + vf • t<br />
2<br />
(3) d = v0t + 1<br />
2 at2<br />
(4) v2 f = v2 0 + 2ad<br />
1. What is the initial velocity of a car accelerating east at 3.0 m/s 2 for 5.0 s and reaching a final velocity of<br />
25.0 m/s east?<br />
2. If we assume acceleration is uniform, how far does a plane travel when it lands at 16.0 m/s west and comes to<br />
rest in 8.0 s?<br />
3. What is the stopping distance of a car if it accelerates at –9.29 m/s 2 and has an initial velocity of 100 km/h.<br />
