Question

Landing with a speed of 81.9 m/s, and traveling due south, a jet comes to rest in 949m. Assuming the jet slows with constant acceleration, find the magnitude and direction of its acceleration.

Answer 1

v² = v²o + 2a(x - xo) → a = (v² - v²o)/(2(x - xo)) = (0² - (81.9 m/s)²)/(2(949 m)) = -3.53 m/s² → 3.53 m/s² to the north
