Q.4 A horizontal block-spring system with the block on a frictionless surface has total 30 mechanical energy equal to 47.0 J and a maximum displacement of 0.240 m from equilibrium position (a) What is the spring constant? (b) What is the kinetic energy of the system at the equilibrium position? (c) If the maximum speed of the block is 3.45 m/s, what is its mass? (d) What is the speed of the block when its displacement is 0.160 m? (e) Find the maximum acceleration of the block and where does it occur? () Determine the displacement, x, of the particle from the equilibrium position at t 0.500 s. (g) Suppose the same system is released from rest at x 0.240 m on a rough surface so that it loses 14.0 J by the time it reaches its first turning point (after passing equilibrium at x-o). What is its position at that instant?
