a vertical pole of height h, that can rotate about a hinge at the bottom. The pole is held in position by two wires under tension.
What is the ratio of the tension in the left wire to the tension in the right wire? Suppose that θ1 = 73 ∘ and θ2 = 17 ∘.

PHYSICS IS h FUN !! A sign has a mass of 1050 kg, a height h = 1 m, and a width W = 4 m. It is held by a light rod of length 5 m that is perpendicular to a rough wall. A guy wire at 23° to the horizontal holds the sign to the wall. Note that the distance from the left edge of the sign to the wall is 1 m. Suppose we rely upon friction...

A uniform sheet of metal in the shape of a hemisphere of radius 1 m is used as a sign. The hemisphere has a mass of 200 kg and is suspended by two vertical wires attached to points along its horizontal diameter. One wire is attached to the left end of the diameter and the other is attached to a point three-quarters of the way to the other end. What is the tension in each wire? A ladder...

1. KINEMATICS: Kickoff During kickoff for the Oakland Raiders, Sebastian Janikowski's powerful left leg launches the ball from the 30-yard line with the initial velocity of 30 m/s. a. Assuming no air resistance, can the ball reach the end of the field, i.e. travel at least 80 yards (73 m), resulting in a touch-back? Please explain (a yes or no answer is not sufficient) b. Assuming Mr. Janikowski chose the best possible angle for the kick, how long is the...

1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
3. This problem revisits the question from Problem Set I about finding the dimensions of a one-liter can that will have the minimum cost. We will now approach it using calculus methods. In class, we found the dimensions of a right circular cylinder (a “can") that has a volume of 1,000 cm3 using the minimum possible material. This assignment changes that problem slightly by seeking the minimum cost for a right circular cylinder whose volume is 1,000 cm3 where the...
