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. Use the analytical method to find the resultant vector of all her displacement vectors. What is its magnitude and direction?

In Jules Verne’s 1865 story with this title, three men went to the moonin a shell fired from a giant cannon sunk in the earth in Florida.(a) Find the minimum muzzle speed needed to shoot a shell straightup to a height above the earth equal to the earth’s radius RE. (b) Findthe minimum muzzle speed that would allow a shell to escape from theearth completely (the escape speed). Neglect air resistance, the earth’srotation, and the gravitational pull of the moon. The earth’s radius andmass are RE = 6.37 * 10^6 m and mE = 5.97 * 10^24 kg.
The below figure shows a pump that transfers a steady stream of 35◦API crude oil from an oiltanker to a refinery storage tank, both free surfaces being open to the atmosphere. Theeffective length—including fittings—of the commercial steel pipe is 6,000 ft. The dischargeat point 4 is 200 ft above the pump exit, which is level with the free surface of oil in thetanker. However, because of an intervening hill, point 3 is at a higher altitude than point 4.Losses between points 1 and 2 may be ignored.The crude oil has the following properties:Density ρ = 53 lbm/ft 3 ; Viscosity μ = 13.2 cP; Vapour Pressure Pv = 4.0 psia Answer the following questions:1. If the flow in the pipeline were at the upper limit of being laminar, what pump exitpressure would then be needed? (Answer this part without using the friction factor plot

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
