5. For the system shown below A and C are at rest. Complete the following: a) Calculate spring constant such that block B will be displaced 240 mm when lowered slowly b) Using a spring constant of 2 kN/m. Determine the velocity of C when it has dropped 315 mm Note: Spring is initially at its free length. All Assumption must be stated Spring constant initially unknown (25 marks) (7 marks) (18 marks) Pulley inertia carnot be ignored Weight 100 kg Diameter 250 mm 300 mm www B 500 mm Free length ~500 rpm C 300 kg A LAWA Cylinder A diameter AIO WA Weight 200 kg 5.
