Tarzan wants to swing on a vine across a river. He is standing on a ledge above the water's edge and the river is 5m wide. The vine is attached to a tree branch that is 8m directly above the opposite edge of the river. Initially the vine makes a 60 degree angle with the vertical as he is holding it. He swings across starting from rest, but unfortunately the vine breaks when the vine is 20 degrees from the vertical. (a),Assuming Tarzan weighs 900N,what was the tension in the vine just before it broke? (b) Does he land safely on the other side of the river

Tarzan jumps from a cliff and grabs a vine. He jumps horizontally from the cliff with initial velocity v0 at the time t0. The vine has mass M and length L. Initially, the vine is hanging straight down and is attached at its highest point, O. After the “collision” Tarzan remains attached to the vine with his center of mass at the lower edge of the vine. Tarzan’s mass is m. The vine behaves as a rod attached without friction...

Tarzan, who has a mass of 80 kg, holds onto the end of a vine that is at a 13 ∘ angle from the vertical. He steps off his branch and, just at the bottom of his swing, he grabs onto his chimp friend Cheetah, whose mass is 50 kg. What is the maximum angle the rope reaches as Tarzan swings to the other side? Express your answer in degrees.

Tarzan, who has a mass of 85 kg, holds onto the end of a vine that is at a 13 ∘ angle from the vertical. He steps off his branch and, just at the bottom of his swing, he grabs onto his chimp friend Cheetah, whose mass is 30 kg. What is the maximum angle the rope reaches as Tarzan swings to the other side?

A scientist wishes to estimate the average depth of a river. He wants to be 95% confident that the estimate is accurate within 3 feet. From a previous study, the standard deviation of the depths measured was 5.48 feet. How large a sample is required? The lifetime of a certain brand of battery is known to have a standard deviation of 23 hours. Suppose that a random sample of 100 such batteries has a mean lifetime of 39.1 hours. Based...

A child swinging on a swingset with chains of length l wants to swing and jump off the swing to get as far as possible. At what angle θ_jump should the child let go of the swing to maximize the landing distance? What is the distance jumped as a function of θ_jump? Results should be functions of θ_jump and variables/parameters which should be introduced as required. Model swinging using simple pendulum and jumping using projectile motion. Note, the child is...

A person wants to catch the bus. Standing on the side of the street, the person sees the bus, 150 meters to the left appraoching at 24.6 m/s. The bus stop is located 50 meters to the right. Already, the bus is slowing-down at 1.45 m/s^2 so the person immediately begins jogging towards the bus stop at a constant 3.12 m/s. (a) Which one gets to the stop first, (b) how long must it wait for the other, and (c)...

Michael Faraday unsuccessfully attempted to measure the potential difference across the River Thames due to the flow of water (which is a good conductor due to dissolved salts) in the earth's field. At Waterloo Bridge, where Faraday made his attempt, the river is 200 m wide and flows eastward at 2.4m/s . The earth's magnetic field here has a magnitude of 50 ?T and is tipped 65?from the horizontal, so it has both horizontal (north) and vertical (down) components. Part...

A tall tree is growing across a river from you. You would like to know the distance between yourself and the tree,as well as its height, but are unable to make the measurements directly. However, by using a mirror to form an image of the tree and then measuring the image distance and the image height, you can calculate the distance to the tree as well as its height. Suppose that this mirror produces an image of the sun, and...
