- At time t=0, a disk of radius 1 m starts to roll without slipping on a horizontal plane with an angular acceleration of α=(2/3) rad s -2. A small stone is stuck to the disk. At t=0, it is at the contact point of the disk and the plane. Later, at time t=√π s, the stone detaches itself and flies off tangentially from the disk. The maximum height (in m ) reached by the stone measured from the plane is (1/2)+(x/10). The value of x is [ [Take g=10 m s -2.]
