Using Equations of Accelerated Motion

1. A car moving at a velocity of 22 m/s [N] accelerates at a constant rate of 1.4 m/s2 [N] for 3.0 s. What is the displacement of the car in this time?

2. A car increases its speed from 24 m/s [W] to 32 m/s [W] over a distance of 84 m. What is the car's average acceleration during this time?

3. A car travels north a distance of 86.4 m along a straight stretch of road for 12.0 s with a constant acceleration of 1.20 m/s2 [N]. Assuming the car started from rest, what was the car's final velocity?

4. A bicyclist increases his velocity from 1.6 m/s [S] to 2.2 m/s [S] during a time interval of 6.8 s. Assuming the biker maintained a constant acceleration, what was the bicyclist's displacement during this time?

5. A helicopter increases its speed from 12 m/s [E] to 14 m/s [E] during a time interval of 4.6 s. What was the helicopter's average acceleration?
