A flywheel with a radius of 0.310m starts from rest and accelerates with a constant angular acceleration of 0.660rad/s2.
Part A Compute the magnitude of the tangential acceleration, the radial acceleration, and the resultant acceleration of a point on its rim at the start.
Part B Compute the magnitude of the tangential acceleration, the radial acceleration, and the resultant acceleration of a point on its rim after it has turned through 60.0?.
Part C Compute the magnitude of the tangential acceleration, the radial acceleration, and the resultant acceleration of a point on its rim after it has turned through 120?
A person of mass 72-kg stands at the center of a rotating merry-go-round platform of radius 2.80 m and moment of inertia 930 kgcdot m^2. The platform rotates without friction with angular velocity 2rad/s. The person walks radially to the edge of t..
A flywheel in a motor is spinning at 560 when a power failure suddenly occurs. The flywheel has mass 40.0 and diameter 75.0. The power is off for 34.0, and during this time the flywheel slows down uniformly due to friction in its axle bearings. Durin..

At a distance rl from point charge the magnitude of the electric field created by charge is 248 N/C. After a distance r2 from the charge, field has a magnitude of 132N/C. Find ration r2/r1.
Some people think that they can stop themselves rushing forward by putting their hands on the dashboard. Find out the mass of the object that has a weight equal to force you just calculated.
What is the net force exerted on the skier, assume his acceleration is constant.
If you weigh 670 on the earth, illustrate what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 19.0?
A rope applies a horizontal force of 180N to pull a crate a distance of 2m across the floor A frictional force of 60N opposes this motion.
