Read each question carefully. Show all your work for each part of the question. The parts within the question may not have equal weight. m A block of mass m is placed on an inclined plane that makes an angle O with the horizontal, as shown in the figure. The coefficients of static and kinetic friction between the block and the surface are us and uk, respectively. Express your answers in parts (b) and (c) in terms of m, 0, Us , Me, and physical constants, as appropriate.It is determined that for this surface, the force of friction is proportional to the speed of the block according to the equation f = - kv, where k is a positive constant. (e) On the axes below, sketch the speed v and the acceleration a as functions of time as the block slides down the incline. -t -t B IU X X2 3 0 2 8 E a Vouminalt --- -t O- 0 / 10000 Word Limit
