At the bottom of a loop in the vertical plane, an airplane has a horizontal velocity of 150 m/s and is speeding up at a rate of 25 m/S². The radius of curvature of the loop is 2000 m. The plane is being tracked by radar at O. What are the recorded values of ř and 0 for this instant? 2000 m 150 m/s 600 m S00 m Or = 120 m/s and 0 = -0.09 rad/s Or = 110 m/s and 0 -0. 19 rad/s Oi = 130 m/s and 0 = 0.19 rad/s %3D Or = 150 m/s and 0 0.09 rad/s %3D

(b) The water is siphoned out of the tank shown in Figure 4 (b). Determine the flow rate from the tank and the pressures at points (1) and (2).

(5) In order to forge a pure gold ring, you first need to purchase the gold. The ring design is a simple band wrapped in a circle, with dimensions given below. Using the Pappus-Guldinus Theorem #2, how many grams of gold are needed for this ring? The density of gold is 19.3 g/cm³. 2 cm 1 cm 0.5 cm 0.5 cm

The U-tube shown in Figure Q3 (a) is rotated about one of its arms at an angular speed of o rad/s. At o = 0 rad/s, the U-tube contains 20-cm-high alcohol in both arms Q3 (a) Determine the new o when the elevation difference between the fluid surfaces in the two arms is 30 cm.
