Modern oil tankers weigh over a half-million tons and have lengths of up to one-fourth miles. Such massive ships require a dista

uranmaximum [27]

Answer:

Acceleration = (change in speed) / (time for the change)

Change in speed= (0 - 26 km/hr) = -26 km/hr

(-26 km/hr) x (1,000 m/km) x (1 hr / 3,600 sec) = -7.222 m/sec

Average acceleration = (-7.222 m/s) / (22 min x 60sec/min) = -0.00547 m/sec²

Average speed during the stopping maneuver =

(1/2) (start speed + end speed) = 13 km/hr = 3.6111 m/sec
