When a jet lands on an aircraft carrier, a hook on the tail of the plane grabs a wire that quickly brings the plane to a halt before it overshoots the deck. In a typical landing, a jet touching down at \(240 \mathrm{~km} / \mathrm{h}\) is stopped in a distance of \(95 \mathrm{~m}\).

a. What is the magnitude of the jet's acceleration as it is brought to rest?

b. How much time does the landing take?
