Mary, is sitting on the very outer edge of a 7-meter diameter merry-go-round. Her friend, Li Mei, grabs onto the merry-go-round and rotates it through an arc of exactly 1 radian. How far did Mary travel (provide the distance in units of meters)?

This question concerns the linear speed of the Great Pyramid in Egypt relative to the centre of the Earth. The angle between the Earth's axis of rotation and the radial line joining the centre of the Earth to the Great Pyramid is 60.0°. Given that the radius of the Earth is 6.38 x 106 m and that 1 sidereal day = 8.62 × 104 s, what is the linear speed of the Great Pyramid relative to the centre of the Earth due to the Earth's daily rotation? Give your answer in scientific notation, correct to 3 significant figures. Linear speed relative to Earth's centre = X² ms-1.

The rod rotates around the z axis in the (x,y) plane. A constant force of 22N in the "y" direction acts on the sphere. a) Assuming that the sphere is a particle, what will be the rotational inertia about the origin? b) If the rod makes an angle of 40° with the positive x-axis, calculate its angular acceleration. 40.- Three particles are connected to a thin rod one meter long and of negligible mass that rotates around the origin in the (x,y) plane. Particle 1 (mass 52g) is attached at a distance of 27cm from the origin, particle 2 (35g) is at 45cm and particle 3 (24g) is at 65cm. a) What is the rotational inertia of the system? b) if instead the rod rotated around the center of mass of the system, what would its rotational inertia be?
