A block of solid brass having a mass of 1.8 kg is placed on one end of a steel plank 4.0 m long. The end with the brass block is slowly raised upwards, forming an inclined plane. You occasionally give the block a small "nudge" to overcome static friction. At what angle, θ, would the block slide down the plane with constant speed?. Derive the working equation from basic principles. Please help me with this!!!. Please provide full explanation and answer!!!.

A block with mass m1 = 8.8 kg is on an incline with an angle θ = 40° with respect to the horizontal. For the first question there is no friction, but for the rest of this problem the coefficients of friction are: μk = 0.38 and μs = 0.418. 1. When there is no friction, what is the magnitude of the acceleration of the block? 2. Now with friction, what is the magnitude of the acceleration of the block...
