Avendor at the local art fair ties her tent to the concrete-filled coffee can shown in (figure 1). the can has a mass of 3 kg, and the rope is pulled at an angle of 40 degrees above the vertical. 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 0.68.

Three point charges, two positive and one negative, each having a magnitude of 20 μc are placed at the vertices of an equilateral triangle (30 cm on a side). what is the magnitude of the electrostatic force on the negative charge

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

Agraduated cylinder contains 63.0 ml of water. a piece of gold, which has a density of 19.3 g/ cm3, is added to the water and the volume goes up to 64.5 ml. calculate the mass in grams of the gold that was added to the water. explain how you got your answer.
