In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day and he is blown along the following directions: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 1.30 km and 25.0 south of west, then 5.10 km straight east, then 1.70 km and 5.00 east of north, then 7.20 km and 55.0 south of west, and finally 2.80 km and 10.0 north of east. Use a graphical method to find the castaway’s final position relative to the island.
The eye of a hurricane passes over Grand Bahama Island in a direction 60.0° north of west with a speed of 44.0 km/h. Three hours later, the course of the hurricane suddenly shifts due north, and its speed slows to 24.0 km/h. How far from Grand Bahama is the hurricane 5.00 h after it passes over the island?? km

QUESTION 6 Supply all missing information with the correct numerical values. Do not include the units. Round off all answers to two decimal places. Do not forget th negative sign (-) if needed. A cannon ball is fired with an initial speed of 123 m/s at angle of 60 degrees from the horizontal. Select to Express the initial velocity as a linear combination of its unit vector components. Vo = ( 61.50 m/s) i +( 106.52 m/s) ? At the maximum height, the speed of the cannon ball is v = 61.50 m/s and the magnitude of its acceleration is a = 9.8 m/s?. The time needed to reach maximum height is t = 10,8 S. The maximum height reached by the cannon ball is H = m.
