Pls find the Question attached Questions 21 and 22 are based on the following physical situationA plank of mass 1.5 kg is placed on a horizontal floor that is lubricatedwith oil. Top of the plank is in level with a platform as shown in thefigure. Force of viscous drag on the plank due to layer of lubricating oil,Plankwhen the plank slides is given by equation / = -kü , where i is in N, iis velocity of the plank in m/s and k = 2.0 kg/s. A small block of mass 0.5kg lands from the platform on the plank with a velocity 10 m/s and aftersliding some distance on the plank, the block stops on the plank.21. How far does the plank slide on the floor?(b) 1.5 m(d) 3.0 m(a) 1.0 m(c) 2.5 m22. Which of the following graph best describes relation between magnitudeof frictional force F between the block and the plank with time t?(a)(b)F4F4(c)(d)

From the momentum conservation between the plank and the block.

Questions 21 and 22 are based on the following physical situation A plank of mass 1.5 kg is placed on a horizontal floor that is lubricated with oil. Top of the plank is in level with a platform as shown in the figure. Force of viscous drag on the plank due to layer of lubricating oil, when the plank slides is given by equation † = -kü , where † is in N, ū is velocity of the plank in m/s and k = 2.0 kg/s. A small block of mass 0.5 kg lands from the platform on the plank with a velocity 10 m/s and after sliding some distance on the plank, the block stops on the plank.
