A battleship simultaneously fires two shells at enemy ships, as shown above. To hit the nearby ship (A), it launches a shell from one gun with a speed of 55.0 m/s at an angle of 72.0o above the horizon. To hit the far ship (B), it launches a shell from another gun with a speed of 92.0 m/s at an angle of 31.0o above the horizon. How much time is there between when each ship is hit?

A boat is docked on the southern shore of a swiftly moving river that is 262.0 m wide. The river flows from east to west with a speed of 4.00 m/s relative to the shore. There is a dock located upstream on the northern side of the river at an angle of 57.0∘57.0∘ relative to the shore (i.e. north of east). The boat is able to travel at a speed of 6.50 m/s relative to the water. If the boat travels directly to the dock on the northern shore at a constant speed, how long does it take to get there?
