Undeformed position 1. (25) A block of mass m = 1.6 kg is placed on a horizontal plane and is attached to a spring of stiffness k 30 N/m that is undeformed when x = 0. The static and kinetic coefficients of friction are μs = 0.3 and μ= 0.2. The block is launched at x = 0 with an initial velocity of 6 m/s to the right. (a) Determine the value of x when the block first comes to rest. (b) Show that the block does not remain at rest in the position determined in (a). (c) Calculate the speed of the block when it reaches x = 0 for the second time. k www Hs=0.3) Mk=0.2 x 1 $2 Undeformed position 1.
