Example 2: After 5.2 seconds of uniform acceleration from rest, a spacecraft reaches an altitude of 5.7 x 102 m [up]. What is the final velocity of the spacecraft? What is the acceleration of the spacecraft? Solution Strategy Example 3: What is the initial velocity of a car that reached 32 m/s [S] in 3.4 s at a rate of 2.6 m/$2 [S] ? Solution Strategy
