Physics

A uniform disk with radius 0.310 m and mass 30.0 kg rotates in ahorizontal plane on a frictionless vertical axle that passesthrough the center of the disk. The angle through which the diskhas turned varies with time according to?(t)=( 1.10 rad/s)t+( 6.90rad/s2 )t2

What is the resultant linear acceleration of a point on the rimof the disk at the instant when the disk has turned through 0.100rev ?
