block of mass m= 2.00 kg is attached to a spring of force constant k =565 N/m as shown in the figure below. The block is pulled to a position xi = 5.60 cm to the right of equilibrium and released from rest. Find the speed the block has as it passes through equilibrium if the horizontal surface is frictionless. Find the speed the block has as it passes through equilibrium (for the first time) if the coefficient of friction between block and surface is µk= 0.350.

Question

A block of mass m= 2.00 kg is attached to a spring of force constant k =565 N/m as shown in the figure below. The block is pulled to a position xi = 5.60 cm to the right of equilibrium and released from rest.

  1. Find the speed the block has as it passes through equilibrium if the horizontal surface is frictionless.
  2. Find the speed the block has as it passes through equilibrium (for the first time) if the coefficient of friction between block and surface is µk= 0.350.
