Question

solid disc angular speed of 200 Radians per second it has constant acceleration 4 Radian per second square find angular displacement to which disc turns before coming to rest.​

Answer 1

Answer:

disc, initially at rest, starts rotating about its own axis, with a constant angular acceleration of 0.2 rad/s2.

Answer 2

Explanation:

Here disc is rest at finally!

So given values are Angular speed (initial) =200

Acceleration (retardation) = - 4

By third eqn of motions

W^2=W,^2+2a theta

0 = 200^2 - 8 theta

Theta =5000 rad

Here it ur ans!

If i done any mistake, make pardon
