The Angular Velocity of a 755-G Wheel 15

question 69

Essay

The angular velocity of a 755-g wheel 15.0 cm in diameter is given by the equation ω(t)= (2.00 rad/s²)t + (1.00 rad/s⁴)t³.
(a)Through how many radians does the wheel turn during the first 2.00 s of its motion?
(b)What is the angular acceleration (in rad/s²)of the wheel at the end of the first 2.00 s of its motion?

Terminal Buttons

The small knobs at the end of an axon that release chemical signals from the neuron into the synapse to stimulate the next neuron.

Stimulation

The activity of promoting or encouraging a physical or biological response through external or internal factors.

All-or-none

A principle stating that the strength of a response of a nerve cell or muscle fiber is not dependent on the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire.
