1) A 0.30-kg ball is attached at the end of a 0.90-m-long stick. The ball and stick rotate in a horizontal circle. Because of air resistance, a continual push must be exerted on the stick to keep the ball moving at a constant speed, causing a 0.036-Nm torque. Draw an extended force diagram showing the forces exerted on the ball and stick and use it to determine the magnitude of the resistive force that the air exerts on the ball opposite its motion. What assumptions did you make?
Item 8 8 of 26 II Review | Constants Part A The parallel axis theorem relates Im, the moment of inertia of an object about an axis passing through its center of mass, to Ip, the moment of inertia of the same object about a parallel axis passing through point p. The mathematical statement of the theorem is I, = Iem + Md², where d is the perpendicular distance from the center of mass to the axis that passes through point p, and M is the mass of the object. Suppose a uniform slender rod has length L and mass m. The moment of inertia of the rod about about an axis that is perpendicular to the rod and that passes through its center of mass is given by Iem = mL. Find Iend, the moment of inertia of the rod with respect to a parallel axis through one end of the rod. Express Iend in terms of m and L. Use fractions rather than decimal numbers in your answer. • View Available Hint(s) {(m) (L²) Iend = Submit Previous Answers v Correct Part B Now consider a cube of mass m with edges of length a.…
