A 5.06 kg block located on a horizontal floor is pulled by a cord that exerts a force F = 13.9 N at an angle theta = 18.0° above the horizontal, as shown in the figure. The coefficient of kinetic friction between the block and the floor is 0.06. What is the speed of the block 3.5 s after it starts moving?© BrainMass Inc. brainmass.com February 24, 2021, 2:14 pm ad1c9bdddf
Denote the supporting force by N, and denote the gravity by Mg. Denote the friction force by f and denote the force pulling the block by F. The directions of these kinds of forces are shown above. We denote the coefficient of kinetic friction between the block and the floor by .
Now we try to ...
With good diagrams and explanations, along with step by step calculations to determine the speed of block, the problem is solved in an attached Word document.
