Walking by a pond, you find a rope attached to a tree limb 6.0 m off the ground. You decide to use the rope to swing out over the pond. The rope is a bit frayed but supports your weight. You estimate that the rope might break if the tension is 72 N greater than your weight. You grab the rope at a point 4.6 m from the limb and move back to swing out over the pond. Assume your weight to be 650 N (about 145 lb).
(a) What is the maximum safe initial angle between the rope and the vertical so that it will not break during the swing?
(b) If you begin at this maximum angle, and the surface of the pond is 1.2 m below the level of the ground, with what speed will you enter the water if you let go of the rope when the rope is vertical?
A surface completely surrounds a 3.5 × 10-6 C charge. Find the electric flux through this surface when the surface is (a) a sphere with a radius of 0.59 m, (b) a sphere with a radius of 0.16 m, and (c) a cube with edges that are 0.27 m long.
