On a sailboat, the wind coming at you from directly ahead can't be used to push you forward. However the wind blowing sideways across the boat can be used to propel the boat forward. Relative to due north, the boat is facing in the direction of 43°, while the wind is blowing in the direction of 270°. If the wind speed is 8 m/s, how fast is the part of the wind blowing sideways across the deck (magnitude only)?

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 she is blown along the following straight lines: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 130 km and 25.0 of west, then 5.10 km due 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.

a) A wind turbine with two or four hollow hemispherical cups connected to a pivot is commonly uscd to measure wind speed. Consider a wind turbine with four 8-cm- diameter cups with a center-to-center distance of 40 cm, as shown in Fig. PI1-35. The pivot is stuck as a result of some malfunction, and the cups stop rotating. For a wind speed of 15 m/s and air density of 1.25 kg/m3, determine the maximum torque this turbine applies on the pivot. A hemisphere at two different orientations for Re > 10 40 cm C04
