The following objects have velocity and mass as given: object a: m=5 kg, ⃗v=−11 ^j object b: m=6 kg, ⃗v=5^ i +8.7 ^ j object c: m=10 kg, ⃗v=−10 ^i find the x- and y-components of the net momentum of the system objects if we define the system to consist of (a) objects a and c (b) objects b and c (c) objects a, b, and c

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.
