A 4.5kg suitcase on a platform was pulled by a lady. She applied 50 N at an angle 20 degrees above horizontal. The kinetic coefficient of friction between the suitcase’ wheel and the platform is 0.2. If the suitcase was displaced 20m after 1 min. Find Fn *show the complete solution  *don't forget to put the unit after the final answer *use 9.81 m/s squared for acceleration *round off into 4 decimal places

* for ce of friction is I57 N A 32 kg block sits on a table. This block is attached by a string to a second block that hangs. The string runs over a pulley, as shown below. What is the maximum mass of the hanging block that will allow the 32 kg block to remain stationary? 10. 32Kg

Choose the correct answer choice. Answer must be in scientific notation with SI units that do not have prefixes except for kg. (m/s NOT cm/s). Answer must be in standard scientific notation

PRINTER VERSION 1 BACK Chapter 07, Problem 007 Your answer is partially correct. Try again. A 4.6 kg body is at rest on a frictionless horizontal air track when a constant horizontal force F acting in the positive direction of an x axis along the track is applied to the body. A stroboscopic graph of the position of the body as it slides to the right is shown in the figure. The force F is applied to the body at t = 0, and the graph records the position of the body at 0.50 s intervals. How much work is done on the body by the applied force F between t = 0 and t = 1.8 s? rt%3D0 0.5 s -1.0s 1.5 s 2.0 s- LIT 0.2 0.4 0.6 0.8 x (m) Number To.8 Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work SHOW HINT LINK TO TEXT LINK TO SAMPLE PROBLEM VIDEO MINI-LECTURE search 9:06 PM ENG 4/4/2021 SUS pgup pgdn 17 end prt sc pause insert delete break %23 3 5. 6. backspac
