Agyroscope flywheel of radius 3.21 cm is accelerated from rest at 13.2 rad/s2 until its angular speed is 2450 rev/min.
(a) what is the tangential acceleration of a point on the rim of the flywheel during this spin-up process?
(b) what is the radial acceleration of this point when the flywheel is spinning at full speed?
(c) through what distance does a point on the rim move during the spin-up?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
