A truck accelerates uniformly from rest and after 5 seconds the 50−cm radius wheels on the truck have an angular velocity ωf = 47 rad/s. (a) What is the magnitude of the angular acceleration, α, of the wheels? α = rad/s2 (± 0.1 rad/s2) (b) What is the magnitude of the final velocity, vf, of the truck? vf = m/s (± 0.1 m/s) (c) Through what total angle does each wheel turn in this time? θ = rad( ± 1 rad)

Several species of mollusks and clams produce a crystalline style, a cylindrical protrusion 5.00 mm in length and 0.800 mm in diameter, in their stomach to act as a capstan and aid in the digestion process. The style is rotated about its long axis at an average speed of 12.0 rpm, and typically dissolves after 2.00 h. (a) What is the angular acceleration (in rad/s s2 ) of the style if, starting from rest, it reaches a rotation speed of 12.0 rpm in 12.5 s? rad/s2 (b) What is the angle (in rad) through which the style rotates to reach its final rotational speed after 12.5 seconds? rad (c) What is the rotational kinetic energy (in J) of the 3.00 g style once it reaches its final rotational speed after 12.5 seconds? J
