It is desired that the outer edge of a grinding wheel 9.0 cm in radius move at a rate of 6.0 m/s.

The angular speed is___rad/s.
A thread of length m could be wound on the rim of the wheel in 3.0 s when it is turning at this rate?
Nearest whole number.

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

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
