- The figure below represents a bicycle wheel comprised of a rim with a radius of R = 0.5 m and mass of M = 200 g, to which someone has added two m = 30 g sensors that are separated by an angle of = 110°. The axis of rotation for the wheel is at its center, as represented by the vector symbol, for a direction into the page. m = 30 g R = 0.5 m M = 200 g m = 30 g a) Where is the center of mass of the wheel/sensor system? b) What is the rotational moment of inertia of the wheel/sensor system around its axis of rotation?A solid, uniform, spherical boulder (I=(2/5) MR2) starts from rest and rolls down a 75.0 [m] hill, as shown at the figure at the right. The top half of the hill is rough enough to cause the boulder to roll without slipping, but thelower half is covered with ice and there is no friction. What is the translational speed of the boulder when it reaches the bottom of the hill?A gardener is using a tool as shown in the figure to pull weeds. 24 cm You will notice that the tool is designed with a built-in pivot point about which the torques are applied. If the gardener applies a 1.77 Nm torque (about the pivot point) in order to pull a weed, determine the resistive force (in N) the weed exerts on the weed puller. N

Answer the following questions if you pull out at A and push in at B along the axis of the disk.What is the direction of the torque acting on the disk? What is the direction of the initial angular momentum vector for the disk? The applied torque causes the wheel's axis (or angular momentum vector) to move.
