During takeoff, a plane accelerates at 4 m/s^2 and takes 40 s to reach takeoff speed. What is the velocity of the plane at takeoff?

7. 𝑣 𝑓 = 𝑣 𝑖 +𝑎(∆𝑡)
A car with an initial speed of 31.4 km/h accelerates at a uniform rate of 1.2 m/s^2 for 1.3 s. What is the final speed and displacement of the car during this time?

8. ∆𝑥= 𝑣 𝑖 ∗ ∆𝑡+ 1 2 𝑎 ∆𝑡 2
𝑣 𝑓 = 𝑣 𝑖 +𝑎(∆𝑡)

9. 𝑣= ∆𝑥 ∆𝑡
The peregrine falcon is the fastest of flying birds (and, as a matter of fact, is the fastest living creature). A falcon can fly 1.73 km downward in 25 s. What is the average velocity of the falcon?
