A sanding disk with a rotational inertia of 1.2 x 10-3kgm2 is attached to an electric drill whose motor delivers a torque of 16 Nm. If the torque is applied for 25 ms and the disk starts from rest, what is the magnitude of the angular velocity of the sanding disk? Use the rotational version of the Impulse Momentum Theorem. Take note of the time units.
Wind energy is gaining increased attention, generating an increased interest in windmill technology. Because windmill blades (vanes) rotate about a central axis, one of the most important physical properties of a windmill is its moment of inertia. Given is a picture of a typical windmill, where the geometry and center of mass of one of the vanes is illustrated. The mass of each vane is 411 kg. The distance from the center of mass of the vane to axis B is k₁ = 2.75 m. The distance from the center of mass of the vane to the center of the windmill hub is k₂ = 4.26 m. If the moment of inertia of a vane about axis A is 241 kg⋅m² and about axis B is 5860 kg⋅m², calculate the moment of inertia Itotal of the entire assembly about the axis that passes through the windmill's hub and is perpendicular to the screen. (Ignore the hub and assume the vanes are flat.) I total = kg.m² Center of mass A B
1. in the figure, a solid 0.2 kg ball with radius 0.4 m rolls smoothly along a horizontal frictionless plank with linear velocity of 4 m/s before elastically colliding with another solid ball of mass 0.1 kg standing at rest on the top of the ramp at height H = 7 m. After the collision 0.1 kg ball rolls smoothly down the ramp until it reaches the horizontal section at the end of the track, at height h = 2 m, and flies off the ramp. What will be the velocity of the second ball just before it flies off the ramp? %3D
