A block with mass m = 0.450 kg is attached to one end of an ideal spring and moves on a horizontal frictionless surface. The other end of the spring is attached to a wall. When the block is atx = +0.240 m, its acceleration isax = -14.0 m/s2 and its velocity isvx = +4.00 m/s.
Part A: What is the spring's force constant k?
Part B: What is the amplitude of the motion?
Part C: What is the maximum speed of the block during its motion?
Part D: What is the maximum magnitude of the block's acceleration during its motion?
