Friction Be able to calculate, for both kinetic and static friction: a. The frictional force, given the mass and coefficient of friction, including experimental uncertainty. b. The coefficient of friction, given the mass and frictional force, including experimental uncertainty. c. The mass or the normal force, given the friction coefficient and the applied frictional force, including experimental uncertainty. Be able to sketch a force diagram for a block either at rest or sliding, with friction. Example 1: A block of wood with a mass of 220 g (assumed exact) is sitting on a surface, where the coefficients of static and kinetic friction between the materials are μ = 0.31±0.01, Mk = 0.22 +0.01. What force is required to get the block moving? Quote your answer including an experimental uncertainty. (0.67N ± 0.02N) Once the block is moving, what horizontal force is required to keep the block sliding at constant speed? Quote your answer including an experimental uncertainty. (0.47N ± 0.02N)…

Instructions: Your task is to create a model in response to the prompts in the question below. Be sure to apply a model from this class and include the relevant diagram(s) for that model. And don’t forget to use the Claim, Evidence, Reasoning framework to present your solution. Phenomenon: Runaway Truck Ramp A truck was driving on a highway at 30 m/s when its brakes gave out. The driver steered it onto a “runaway truck ramp”, consisting of an upward ramp (rising 12 meters vertically over 120 meters horizontally), and ending with a compressible barrier which you can model as a giant spring with spring constant “k”. The compressible barrier can be compressed by a maximum 0.5 meters before it stops working. Graphic attached Values: Mass of the truck: 20 metric tons (1 metric ton = 1000kg). Mass of the driver: Choose a reasonable value. Truck Ramp Dimensions: 12 meters vertical, 120 meters horizontal Spring constant k= 6.0 x 107 J/m2. Part 1: Big…
