5.DETAILSA light spring obeys Hooke's law. The spring's unstretched length is 33.0 cm. One end of the spring is attached to the topof a doorframe and a weight with mass 7.00 kg is hung from the other end. The final length of the spring is 42.0 cm.(a) Find its spring constant (in N/m).N/m(b) The weight and the spring are taken down. Two people pull in opposite directions on the ends of the spring, each witha force of 160 N. Find the length (in m) of the spring in this situation.m(c) What If? What would be the length (in m) of the spring if it were now attached to the vertical portion of thedoorframe and stretched horizontally by a single person exerting a force of 160 N?mSubmit AnswerDETAILSLet B = 4.70 m at 60.0°.

You pull on a string with a horizontal force of magnitude Fyb = 69 N that is attached to a block of mass m 6 kg, then to the axle of a solid cylinder of mass me = 4.4 kg and radius r = 0.5 m, then to a spring of spring constant k = 115 N/m. This is all done on an inclined plane where there is friction (μs = 0.65 and μk = 0.36), and the incline angle is 0 = 30 degrees. Everything starts at rest, and the spring is unstretched. The block slides down the plane, the cylinder rolls down the plane (without slipping), and the spring stretches. k lllllllll Fyb b 0 Speed First, what is the speed of the block and cylinder after you have pulled the block and cylinder 172 cm down the plane?
