QUESTION 7 A smаll steel bаll is releаsed at the surface оf sоme оil of known viscosity and begins to sink. The diagrams show the forces acting on the ball shortly after its release and when it has reached terminal velocity. Right click on the button to open the diagram of the falling steel ball in a new window. 7.1 Identify forces X, Y and Z. (3) 7.2 Copy the axes and sketch a velocity-time graph for the motion of the steel ball. Right click on the button to open a diagram of the axes in a new window. (2) 7.3 A student uses Stokes’ law to calculate force Y. State the measurements the student should make to calculate force Y acting on the ball when it is moving at terminal velocity. (2) 7.4 After reaching terminal velocity, the steel ball took 10 seconds to fall through 30 cm of oil. Calculate the terminal velocity of the steel ball. (2) 7.5 The steel ball has a radius of 0,3 cm and the viscosity of the oil is 0,5 Pa.s. Calculate the viscous drag. (3)
