1. The problem statement, all variables and given/known data A 747 Jumbo Jet must reach a speed of 290km/h by the end of the runway to lift off. The 15L-33R runway at Toronto International Airport is 2,770 meters long. The main Toronto Island Airport runway 08-26 is 1216 meters long. Assuming the jet has a constant acceleration, for each runway: a) Determine the time to reach the end of the runway b) Determine the required acceleration. c) Do you think 747’s will ever take off and land on the island? Explain in 3 or 4 lines 2. Relevant equations t = d/s v = u + at v^2 = u^2 + 2ax where u = initial velocity, x = displacement 3. The attempt at a solution a) 290 km/h = 80.5 m/s Runway A) t = 2770/80.5 = 34.4 s Runway B) t = 1216/80.5 = 15.1 s b) Can I assume initial velocity to be 0 and then just use the formulas? Can I also just use the constant acceleration formulas to calculate time for part a)? Because when I do try that and input initial velocity as 0, then the values I get for time are exactly two times the values I got in part a) using t = d/s. Why is this the case? Thanks a lot.
