Strand: Process data and report results Research question: What is the appropriate distance for runway of airport for the airplanes (Lockheed SR-71 Blackbird)?
1-Search the internet (from credible and reliable sources) to get the velocity of Lockheed SR-71 Blackbird airplane (which is type of doy plane)

2-Assume that we want to design an airport runway for Lockheed SR-71 Blackbird airplane, if they will start from rest, with acceleration 2230057 km\h2.
Using the appropriate kinematics equation, state the suitable distance for runway airport. (Use the velocity you got in question (1) as your final velocity

Aspring has a relaxed length of 33 cm (0.33 m) and its spring stiffness is 6 n/m. you glue a 76 gram block (0.076 kg) to the top of the spring, and push the block down, compressing the spring so its total length is 15 cm. you make sure the block is at rest, then at time t=0 you quickly move your hand away. the block begins to move upward, because the upward force on the block by the spring is greater than the downward force on the block by the earth. calculate y vs. time for the block during a 0.09-second interval after you release the block, by applying the momentum principle in three steps each of 0.03-second duration.
