- The coefficient of static friction between an 8 kg box at rest and a 35° inclined plane is 0.70. Determines whether the object starts moving or stays in a static state. Justify your answer. If the object starts moving, what happens to the coefficient of friction? Also, describes the movement of the box.F(t) Force_Crate Known values: Mass of Block 68 kg TT Hs μk 0 0.63 0.53 26° Problem Statement: A crate is initially at rest on a sloped surface, when a force is applied: F(t) where t is in seconds. Answers: When t=44.47 seconds, the crate has not yet started moving. Find the magnitude of the friction force at that time: 317.771 N The direction of the friction force at that time is: down the slope Find the time required for the crate to start moving: Find the crate's speed when t=174.9 s: 9.485 m/s Be sure to include units with your answers. 169.756 S 240+0.2 N,The coefficient of static friction between Teflon and scrambled eggs is about 0.029.
