Suppose that a particle of mass m is in a fluid medium and is given an initial velocity vo to the right from the origin. in class we showed that fluid drag is proportional to velocity at very low speeds but proportional to v at higher speeds. to capture this shift, the best force law to use is f( -cv, where b and c are properties of the fluid. (note that v > 0 always, so f < 0 always.) (a) state the general way to solve for vx) directly (without having to solve for the time- evolution) when the force varies only with velocity, f-f(v). find the distance the particle travels before coming to rest. problem with fbv, and by taking the limit c-0 in your solution for part (b). (for the (b) find v(x) for this system, and use it to sketch a complete phase portrait for this system. (c) show that v(x) becomes a straight line if c-0. do this in two ways. by redoing the

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
