Can you please do question 1 g,h,i Question 1:Consider a block of mass m attached to a spring with forceconstant k, as shown in the figure. The spring can be eitherstretched or compressed. The block slides on a frictionlesshorizontal surface, as shown. When the spring is relaxed, theblock is located at x =0. If the block is pulled to the right adistance A and then released, A will be the amplitude of theresulting oscillations.Assume that the mechanical energy of the block-springsystem remains unchanged in the subsequent motion of theblock.wwwwwwwww-A0a) After the block is released from x = A, it will:remain at rest.move to the left until it reaches equilibrium andstop there.move to the left until it reaches x = -A and stopthere.a.b.C.move to the left until it reaches x = -A and thenbegin to move to the right.The time it takes the block to complete one cycle is called theperiod.

If the block is pulled to the right a distance A and then released, A will be the amplitude of the resulting oscillations. Assume that the mechanical energy of the block-spring system remains unchanged in the subsequent motion of the block. k how m
