A block lies on a horizontal frictionless surface and isattached to the free end of a spring, with a spring constant of 60N/m. Initially, the spring is at its relaxed length and the blockis stationary at position x = 0. Then an applied force with aconstant magnitude of 3 N pulls the block in the positive directionof the x axis, stretching the spring until the block stops. Assumethat the stopping point is reached. What is the position of the block?
