A small block of mass (M) is given an initial speed Vo up a ramp inclined at angle (theta) to the horizontal. It travels a distance (d) up the ramp and comes to rest.
Determine a formula for the coefficient of kinetic friction between block and ramp.
Express your answer in terms of the variables V(knot), m, theta, and d and appropriate constants.
