The Mariana trench is located in the Pacific Ocean at a depth of about 11 000 m below the surface of the water. The density of seawater is 1025 kg/m3.
(a) If an underwater vehicle were to explore such a depth, what force would the water exert on the vehicle's observation window (radius = 0.131 m)?
(b) For comparison, determine the weight of a jetliner whose mass is 4.30 × 105 kg.
An airplane is flying with a velocity of 81.6 m/s at an angle of 18.0 above the horizontal. When the plane is the distance 123 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from t..
