A swing with a beautiful sea view is hung from a tree branch that is found to obey Hooke's law so that when a 20-kg load (a person sits on the swing with a mass of 20-kg ) the branch sags 10 cm. a) How much will the branch sag if a 40-kg mass gets on the swing. b). How much will the branch sag if a 60-kg mass gets on the swing?

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.
