Complete the following acceleration calculations. Show your work.
1. An airplane accelerates down a runway at 3.70 m/s2 for 51.3 seconds until lifting off. Determine the distance it traveled before liftoff.
2. A tennis ball is hit, giving it a horizontal velocity of 81 m/s [E]. Air resistance causes a constant acceleration of 4 m/s2 [W]. Determine its velocity after 3.3 s.
