A block is at rest on a plank whose angle can be varied. The
angle is gradually increased from 0 deg. At 32.9°, the
block starts to slide down the incline, traveling 2.80 m down the
incline in 1.50 s. Calculate the coefficient of static friction
between the block and the plank.

Consider a block of wood given an initial velocity directed up an incline of angle θ. It reaches some maximum distance up the incline, turns around, and slides back down. There is friction present. Take the motion of the block to be after any push necessary to provide the initial velocity. (a) Draw and label separate free body diagrams (FBDs) for (i) the motion up the incline and (ii) the motion back down. Include coordinate axes and indicate acceleration. (b)...

A box is placed on a plank. One end of the plank is gradually raised. When the angle of inclination with the horizontal reaches 30, the box starts to slip, and then slides 2.5 m down the plank in 4.5 seconds. Find the Coefficient of static friction, and (b) coefficient of kinetic friction between the box and the plank.
