a 5.00 g spider is lowering itself to the floor. Its web has a tensile strength of 3.00 x 10-2N. What is the minimal accerleration with which the spider can lower itself? So i dont know how to begin, would the tensile strength of the web be equal to the total forces? as it is equal to force of gravity and normal force? what would the steps be and how to get the answer and whats the answer? thanks a bunch!
