To take off from the ground, an airplane must reach a sufficiently high speed. The velocity required for the takeoff, the takeoff velocity, depends on several factors, including the weight of the aircraft and the wind velocity. 1.) A plane accelerates from rest at a constant rate of 5.00m/s2 along a runway that is 1800m long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time tTO needed to take off?...

11. A DC-8 airplane reaches its takeoff speed of 78 s in a time of 35 s after starting from rest. What is its average acceleration? 14. The tires of a car begin to lose their grip on the ad at an acceleration of 5 m/s2. At this acceler- ation, how long does the car need to reach a speed of 25 m/s starting from 10 m/s?

The cheetah can reach a top speed of 114 km/h (71 mi/h). While chasing its prey in a short sprint, a cheetah starts from rest and runs 46 m in a straight line, reaching a final speed of 95 km/h. (a) Determine the cheetah's average acceleration during the short sprint. m/s2 (b) Find its displacement at t = 3.2 s. (Assume the cheetah maintains a constant acceleration throughout the sprint.) m

An airplane flies horizontally with a constant speed of 158.0 m/s at an altitude of 1320 m. A package is dropped out of the airplane. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. (a) How long (in seconds) is the package in the air before hitting the ground? (b) If the package is released from the airplane at x0 = 0, at what x (on meters) does it hit the ground?
