Asked by Mona
A uniform disk with radius 0.320m and mass 28.0kg rotates in a horizontal plane on a frictionless vertical axle that passes through the center of the disk. The angle through which the disk has turned varies with time according to è(t)= (1.20rad/s)t + (8.70rad/s^2)t^2
my solution:
w(t) = 1.2 + 17.4t
a = (17.4)*(0.32) = 5.568 rad/s2
is my answer CORRECT ??

Update ==>
theta (t) = (1.20rad/s)t + (8.70rad/s^2)t^2
theta (t) = (1.20rad/s)t + (8.70rad/s^2)t^2
