Effect of motion in friction calculation

  1. Jun 24, 2011 #1
    In fig.1 (attached), the formula for calculating the angle at which the block will slide down the ramp is tanθ=µ where µ = coefficient of friction.
    Will this change if the ramp and block where moving at a constant velocity(V) in the direction shown as per fig.2 (attached)?

    You didn't attach any figures, but what do you think? How would the equations that lead to the answer you quoted change under constant velocity motion?
