Question

inn rim 0 x=A Consider the spring-mass system above. A block of mass 4.00 kg is attached to the end of a spring with a force constant of k = 600 N/m. The spring is stretched to a position of x A, and then released to oscillate over a frictionless surface. The maximum speed achieved by the block is 3.00 m/s 2. a. What is the maximum displacement A of the spring from equilibrium (the turning point)? b. When the mass is located at half of the spring's displacement (x s A/2), will t have half its maximum speed, more than half its maximum speed, or less than half of its maximum speed? Test your prediction by calculating the speed of the mass when it is located at x - A/2. Does the spring do more work from x = A to x-A/2, or from x = A/2 to x = 0? How does this explain your result in part (b) above? c.

Please show all work. Thanks
