Ablock 0.1 m square, with 5 kg mass, slides down a smooth incline, 30o below the horizontal, on a film of sae 30 oil at 20oc that is d = 0.20 mm thick. if the block is released from rest at t = 0, (a) derive an expression for the initial acceleration. (b) derive an expression for the speed of the block as a function of time. (c) find the speed after 0.1 s. if we want the mass to instead reach a speed of 0.3 m/s at this time, (d) find the viscosity μ of the oil we would have to use.
