A disk initially rotated counterclockwise at 1.0 rad/s, but has a counterclockwise angular acceleration of 0.50 rad/s^2 for 2 seconds. After this acceleration, the disk is at an angle of 6.0 rad.

What is the disk’s angular position when the acceleration started?

Initial angular position of the disc is 3 radian

Explanation:

As we know that the angular acceleration of the disc is given as

initial angular speed is given as

now we know that angular displacement of the disc is given as

now we have

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
