1. Selected Aircraft: Embraer ERJ 145 XR

2. Maximum Takeoff Weight (MTOW) [lbs]:53,131 lbs

3. Engine Type and Rated Thrust [lbs]:Rolls-Royce AE3007 A1E and 7,800

4. Total Available Thrust (sum of all engines for multiengineaircraft) [lbs]: 15,600 pounds

5. Take-off distance at MTOW [ft]: 7,448 ft

Utilizing the above researched information, derive and present(in an instructional way) approaches and solutions to the followingproblems:

1.) If your selected aircraft's takeoff speed at MTOW wasassumed to be 150 kts (i.e., the speed that is reached in the aboveresearched takeoff distance), explain how to find anddetermine:

a. The total acceleration a [ft/s2]during takeoff roll

b. The sum of retarding forces FR [lb](drag + friction) that was present during takeoff

c. The time t [s] it took for thistakeoff

2.) Given the researched knowledge about the aircraft's thrust,explain for a specific airspeed example how to determine the powerP [HP].

3.) For a specific example related to your researched aircraftdata, explain how to determine potentialEPot[ft-lb], kineticEKin [ft-lb], and total energyETot [ft-lb].

4.) For a specific example, explain how the minimum requiredclimb angle AOC [deg] to clear anobstacle can be calculated from knowledge about the obstacle'sheight and its distance from the point of takeoff.
