Agrindstone increases in angular speed from 4.00 rad/s to 12.00 rad/s in 4.00 s. through what angle does it turn during that time if the angular acceleration is constant?

Explanation:

In an uniformly accelerated circular motion, the angle traveled by the object is given by:

Here is the final angular speed, is the initial angular speed and t is the time of the motion. Replacing the given values:

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
