【已刪除】2. Determine the horizontal force P required to raise the 200 Kg block, The coefficient of friction for all suifaces^ (10%) is 0.4,

【已刪除】3. A 2 Kg disk slides on a smooth horizontal table and is connected to an elastic cord whose tension is T=6r N , where r is the radial position of the disk in meters. If the disk is at r=l m and is given an initial velocity,of 4 m/s in the transverse direction, what are the magnitudes of the radial and transverse components of its velocity when r=2 m?
