Hi i need question 9 answer please and thank you

Transcribed Image Text:7) A 5-kg body A is released from rest on a frictionless
circular surface. The body then moves on a horizon-
tal surface CD whose coefficient of friction with the
body is 0.2. A spring having a spring constant K =
900 N/m is positioned at C shown in the diagram.
How much will the spring compress?
K
