Whale sharks swim forward while ascending or descending. They swim along a straight-line path at a shallow angle as they move from the surface to deep water or from the depths to the surface. In one recorded dive, a shark started 50 m below the surface and swam at 0.85 m/s along a path tipped at a 13° angle above the horizontal until reaching the surface. a. What was the horizontal distance between the shark's starting and ending positions?
A commercial jet sets its speed to 525 mph, and points its nose in the direction of 15 degrees west of north (-105 degrees from +x-axis). However, a strong jet stream is blowing at 110 mph at a direction of 20 degrees. The actual resultant velocity of the aircraft is the sum of these two vectors. a. Find the final velocity b. For this airspeed and wind velocity, find the angle west of due north that the nose will need to point in order for the final velocity to be due north.
