You are a coach for the Physics Olympics team participating in a competition overseas. You are given the following sample problem to present to your team of students, which you need to solve very quickly: A person is standing on the midline of a soccer field. At one end of the field, as shown, is a letter D, consisting of a semicircular metallic ring of radius R and a long straight metal rod of length 2R, the diameter of the ring. The plane of the ring is perpendicular to the ground and perpendicular to the midline of the field shown by the broken line as shown. Because of an approaching lightning storm, the semicircular ring and the rod become charged. The ring and the rod each attain a charge Q. What is the electric potential at point P, which is at a position x along the midline of the field, measured from the center of the rod, due to the letter D? Think quickly and use all resources available to you, which include your physics textbook: you are in competition!

- 5. Given: Three forces act on particle P. Force A has a magnitude of 15 N and acts 60° CCW from the positive x-axis. Force B has a magnitude of 60 N and acts along a ray from point P with a slope of -4/3. Force C has a magnitude of 10 N and acts straight left (180° CCW from positive x- axis). Find the Vector Sum: a. Draw a neat, labeled, scaled diagram representing the tip-to-tail vector addition R=A+B+C. Rx = 15cos60+60(3/5) — 10 and Ry = 15sin60-60(4/5) b. Add the three vectors to find the scalar components of the resultant, Rx and Ry. C. Find the magnitude of the resultant R and the angle 0 it makes with the positive x-axis.arrow_forwardA gallon of milk in a full plastic jug is sitting on the edge of your kitchen table. Estimate the vertical distance between the top surface of the milk and the bottom of the jug. Also estimate the distance from the tabletop to the floor. You punch a small hole in the side of the jug just above the bottom of the jug, and milk flows out the hole. When the milk first starts to flow out the hole, what horizontal distance does it travel before reaching the floor? Assume the milk is in free fall after it has passed through the hole, and neglect the viscosity of the milk.arrow_forward4. Given: Three forces act on particle P.

- An observer sitting on a park bench watches a person walking behind a runner. Figure P4.72A is the motion diagram representing what this observer sees. To better reveal the changing distance between runner and walker, five observations (A through E) are shown on five separate lines in Figure P4.72B. To the observer on the bench, both the runner and the walker move to the right, and the gap between them widens. Draw the motion diagram of the runner from the reference frame of the walker.
