Question

A jet lands on an aircraft carrier at a speed of 63m/s . what is it acceleration if it stops in 2sec due to an arresting cable that snags the airplane and brings it to a stop ?

Answer 1

Answer:

Explanation:intial velocity= 63 m/s

final velocity= 0 m/s

time = 2 s

v= u + at

a = (v-u)/t

a= (0- 63)/ 2

= -63/2

=-31.5 m/s²

negative sign indicates retardation
