일반물리학 1 — Motion Along a Straight Line: Problem 41

41 On a defense aircraft carrier, a military jet lands at a speed of 64 m/s. (a) Assuming the acceleration to be constant, what is the acceleration of the jet if it stops in 3.0 s due to the arresting cable that snags it? (b) If the jet first touches at position $x_i = 0$, what is its final position along an $x$ axis lying under its landing path?
