Math Review (a) Convert 47.0 to radians, using the appropriate conversion ratio. (b) Convert 2.35 rad to degrees. (c) If a circle has radius 1.70 m, what is the are length subtended by a 47.0 angle? (See Sections 1.5 and 7.1.)
Answer the question in full details, thank you very much: A uniform, solid 2.5 kg cylinder can rotate about an axis through its center at O. The forces applied are : F1 =45N, F2 =4.3N, F3 = 5.5N,and F4 = 4.8 N. Also, R1 = 10. cmand R3 = 4.2cm. Find the magnitude (in rad/s^2) and direction (+ denotes counterclockwise and — denotes clockwise) of theangular acceleration of the cylinder.
76. Round and Round Little Jay is enjoying his first ride on a merry-go- round. (He is riding a stationary horse rather than one that goes up Av at 4 = 0 %3D and down.) A schematic view of the merry-go-round as seen from above is shown in Fig. 11-47a with a conve- nient coordinate system.

A star rotates with a period of 30 days about an axis through its center. The period is the time interval required for a point on the star's equator to make one complete revolution around the axis of rotation. After the star undergoes a supernova explosion, the stellar core, which had a radius of 1.0 x 104 km, collapses into a neutron star of radius 3.0 km. Determine the period of rotation of the neutron star.

The wheel starts at rest at t = 0, and the radius vector of a certain point Pon the rim makes an angle of 57.3° with the horizontal at this time. At t = 2.00 s, find (a) the angular speed of the wheel and, for point P, (b) the tangential speed, (c) the total acceleration, and (d) the angular position.
