You are spending the summer as an assistant learning how to navigate on a large ship carrying freight across Lake Erie. One day, you and your ship are to travel across the lake a distance of 200 km traveling due north from your origin port to your destination port. Just as you leave your origin port, the navigation electronics go down. The captain continues sailing, claiming he can depend on his years of experience on the water as a guide. The engineers work on the navigation system while the ship continues to sail, and winds and waves push it off course. Eventually, enough of the navigation system comes back up to tell you your location. The system tells you that your current position is 50.0 km north of the origin port and 25.0 km east of the port. The captain is a little embarrassed that his ship is so far off course and barks an order to you to tell him immediately what heading he should set from your current position to the destination port. Give him an appropriate heading angle.

- A group of Boy Scouts on a straight trail headed N30.6 E found the trail led through a briar patch. They chose to walk 156 meters due east along the south edge of the briar patch, then due north along the east edge of the patch back to the trail. How much farther did they walk to avoid walking through the briar patch?arrow_forwardA hiker leaves the base camp and using a compass walks 4 km E, then 6 km S . At the end of the day, the hiker got lost. It is now dark and he is hungry and is scared of the wild animals. How far is the hiker from the base camp? Which direction should be taken to get back to camp?arrow_forwardA person sails down the Ohio River from City A at full throttle and reaches City B 2.0 km away in 11 minutes. It takes him 45 minutes to sail at full throttle upstream back to City A. What is his sailing speed?arrow_forward
- Sarah is traveling 22km due South. She turns 20° S or E for 16km. She then turns due N for 40km, she then moves 14km at 40° S or W. What is her displacement, and direction?arrow_forwardA ship leaves a dock at 13 mph. After an hour, it is seen from a lighthouse 12 miles east of the dock to bear N 12°30' W. How far was it from the lighthouse? What is its bearing from the dock?arrow_forwardA ship leaves its home port expecting to travel to a port 500 km due south. Before it can move, a severe storm comes up and blows the ship 100 km due east. How far is the ship from its destination? In what direction must the ship travel to reach its destination?arrow_forward
- You are participating in a summer internship with the Coast Guard. You have been assigned the duty of determining the direction in which a Coast Guard speedboat should travel to intercept unidentified vessels. One day, the radar operator detects an unidentified vessel at a distance of 20.0 km from the radar installation in the direction 15.0 east of north. The vessel is traveling at 26.0 km/h on a course at 40.0 east of north. The Coast Guard wishes to send a speedboat, which travels at 50.0 km/h, to travel in a straight line from the radar installation to intercept and investigate the vessel, and asks you for the heading for the speedboat to take. Express the direction as a compass bearing with respect to due north.arrow_forwardA commercial jet travels from Miami to Seattle. The jet's velocity with respect to the air is 570 miles per hour, and its bearing is 332°. The jet encounters a wind with a velocity of 50 miles per hour from the southwest. (a) Draw a diagram that gives a visual representation of the problem.arrow_forwardGabby works as an aerial photographer. On one trip she takes off from the airport and flies 52km on a bearing N46°E. She then turns and flies for 43km until she is due east of the airport. How far is Gabby from the airport when she is due east of it? Is there more than one answer, explain.arrow_forward
- An adventurer paddles a kayak across the current in wild river. She appears to an observer sitting on the riverbank to be travelling directly across the river at 90° to the riverbank, and the water velocity is parallel to the riverbank (in other words, downstream). To do this she must paddle at a constant velocity of 1.8 m/s relative to the water at an angle of 28° from the upstream direction. The river is 76 m wide. What is the speed of the water current? From the given options A 0.80 m/s B 1.6 m/s C 2.2 m/s D 1.9 m/sarrow_forwardI can’t figure out the value of A.arrow_forwardSVS is running an outdoor skills competition. The race is made up of three different events that involve a swim, a climb, and a zip line. You begin at point S. The finish is at point F, which is 200m from S in a direction 65° north of west. The first part of the race is a 600m swim to an island, B, due west of S. The second part is a climb up a vertical cliff to point C. Point C is at an angle of elevation of 10°, as seen from point S. The third part is a zip down a zip line from point C to the finish at point F. You can swim at 1.5m/s, climb at 0.75m/s, and zip at 15m/s. Zip ining a) Label all points S, B, C and F on the diagram below. [C1] Climbing 200 m 10 65 600 m Swimming b) How long (in minutes) will it take to complete the race? [C2, T8]arrow_forward
