A small lightweight rocket is attached to a 8-kg disc that is initially at rest. The disc with a radius of 336 mm is connected to a frictionless stationary pivot O via a lightweight rod of length 1.47 metres (top view shown below). The rocked provides a constant 24.5 N force and remains perpendicular to the connecting rod. Assume the disc slides on a frictionless surface. Calculate the magnitude of the reaction force at pivot O 3.9 seconds after the rocket was fired. Give your answer in newtons and round the final answer to two decimal places. F

Forming a shock absorber, two springs of equal length are nested together. If the maximum compression of the springs is 0.25 and the outer spring has a stiffness of Ka = 420 N/m, what stiffness is required of the inner spring Kb?
