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 = 0.184 m)? (b) for comparison, determine the weight of a jetliner whose mass is 3.96 × 105 kg.

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.
