[-/5 Points] DETAILS SERCP11 3.2.P.013. MY NOTES ASK YOUR TEACHER A brick is thrown upward from the top of a building at an angle of 200 to the horizontal and with an initial speed of 12 m/s. If the brick is in flight for 3.4 s, how tall is the building? m 17. [-/6 Points] DETAILS SERCP11 4.3.P.023. MY NOTES ASK YOUR TEACHER A 1,040-N crate is being pushed across a level floor at a constant speed by a force F of 230 N at an angle of 20.0 below the horizontal, as shown in the figure a below. F 20.07 20.0 a b a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.) b) If the 230-N force is instead pulling the block at an angle of 20.00 above the horizontal, as shown in the figure b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a). m/s 18. [-/12 Points] DETAILS SERCP 11 4.5.P.035. MY NOTES ASK YOUR TEACHER Consider the figure below. (a) Find the tension in each cable supporting the 568-N cat burglar. (Assume the angle 8 of the inclined cable is 31.09.) inclined cable IN horizontal cable vertical cable b) Suppose the horizontal cable were reattached higher up on the wall. Would the tension in the inclined cable increase, decrease, or stay the same? O increase O decrease O stay the same 59OF 1:03 PM 2 Mostly cloudy W 4/26/2022
