Hi there, I cannot seem to figure out this question. I got an answer of 14.04 but it is incorrect. Can someone help walk me through this question? A vendor at the local art fair ties her tent to the concrete-filled coffee can shown in the picture below. A stiff breeze comes up and the string becomes taut. What is the maximum value the string tension can have before the can slips? The coefficient of static friction between the can and the ground is 0.36. Thank you!
This is an F=ma questions. Remember that force and acceleration are vectors. (That's what the boldface font means.) 1) A 14kg object accelerates at (2,4) m/s2. Calculate the magnitude of the force on the object, in Newtons. 2) Calculate the mass if F = (200, 300) N and a = (0.9, 0.3) m/s2. Enter 0 if there exists no answer.
