Extracted text: 13:45 พ. 19 ม.ค. 3 67% lailaaanu – pioneer.netserv.chula.ac.th 1 จาก 12 300 N 3/8 The 50-kg block at A is mounted on rollers so that it moves along the fixed horizontal rail with negligible 0.9 m A friction under the action of the constant 300-N force in В the cable. The block is released from rest at A, with the spring to which it is attached extended an initial amount 1.2 m X, = 0.233 m. The spring has a stiffness k = 80 N/m. %3D Calculate the velocity v of the block as it reaches th position B.
