7. A block of mass 1.8 kg is attached to a horizontal spring that has a force constant of 1100 N/m as shown in Figure a. The spring is compressed 3.0 cm and is then released from rest as in Figure b. (A) Calculate the speed of the block as it passes through the equilibrium position x = 0 if the surface is frictionless. (B) Calculate the speed of the block as it passes through the equilibrium position if a constant friction force of 5.0 N retards its motion from the moment it is released. a x=0 b
