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 km/h is stopped in a distance of 95 m. What is the magnitude of the jet's acceleration as it is brought to rest

Respuesta :

Answer:

23.39 m/s²

Explanation:

Initial velocity, u = 240 km/h = 66.67 m/s

Distance moved, s = 95m

Using one of the equations of motion:

v² = u² + 2as

Since the jet comes to rest, v = 0m/s

0² = 66.67² + 2 * 95 * a

=> -190a = 4444.8889

a = -4444.8889/190

a = -23.39 m/s²

|a| = |-23.39| = 23.39 m/s²
