Using air pressure, the 1.1-kg ball forced to move through the tube lying in the horizontal plane and having the shape of a logarithmic spiral as shown in (Figure 1). Figure < 1 of 1 r=0.20.10 F=6N If the tangential force exerted on the ball due to air pressure is 6 N, determine the rate of increase in the ball's speed at the instant = π/2. Express your answer to three significant figures and include the appropriate units. at = Submit Part B O 0 = μÁ Value Request Answer Units What direction does the tangential force act in?

Please don't provide handwritten solution.   Three identical full spheres of mass 3.1kg and Radius R=2.9m are welded together in such a way that the centres of each of them are at (R,0,0), (3R,0,0) and (5R,0,0). The whole system rotates in +XY plane about the axis parallel to z axis and passing through point (6R,0,0). Find the moment of inertia of the whole system. State your answer to the nearest tenth of kgm2.

A bicycle tire is 66 cm in diameter. (a) At what frequency f does the tire rotate when the bicycle is traveling at a speed of 35 km/h? (b) What is the angular frequency ω?

A rotating space station is said to create "artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. The outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. Randomized Variables d = 180 m If the space station is 180 m in diameter, what angular velocity would produce an "artificial gravity" of 9.80 m/s² at the rim? Give your answer in rad/s.
