A fraternity brother finds an old bungee cord at a garage sale and is contemplating on having a bungee jump event. He measures the spring constant of the cord (assume it is a linear spring) by applying a 500 N force to it and measuring a stretch of 2.5 m. Your job is to help him estimate how tall the jump tower should be. He knows the cord is L = 40 m long. he expects the cord to stretch d for an average 60 kg guy like himself, and at maximum stretch he wants his feet to still be 10 m above the ground. Determine: a. The maximum distance, d, the cord would stretch if a 60 kg brother jumped from tower height, H. b. The force developed in the cord at his max stretch position. c. Calculate the expected tower height. d. The velocity of the brother 40 m below from the topmost level of the tower.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

A fraternity brother finds an old bungee cord at a garage sale and is contemplating on having a bungee jump event.
He measures the spring constant of the cord (assume it is a linear spring) by applying a 500 N force to it and measuring a
stretch of 2.5 m. Your job is to help him estimate how tall the jump tower should be. He knows the cord is L = 40 m long,
he expects the cord to stretch d for an average 60 kg guy like himself, and at maximum stretch he wants his feet to still be
10 m above the ground. Determine:
a. The maximum distance, d, the cord would stretch if a 60 kg brother jumped from tower height, H.
b. The force developed in the cord at his max stretch position.
c. Calculate the expected tower height.
d. The velocity of the brother 40 m below from the topmost level of the tower.

Two somewhat heavy people enter an elevator. Based on their weight, the force that they exert on the steel cable (20 meter length, 0.05m diameter, Young's modulus = 2.0 X 1011 Pa) that suspends the elevator car in its shaft is 2500 N. How many mm will the elevator cable stretch?
A light balloon that has a volume 2.50 m³ filled with a helium (pne = 0.179 kg/m*) is tied to a light string of length L = 5.50 m. The string is tied to the ground, forming an "inverted" simple pendulum, as in Figure 2a. If the balloon is displaced slightly from the equilibrium position, as in Figure 2b (Pair = 1.29 kg/m³). Determine a) the spring constant, k, (Hint : Use an analogy with the mass hanging at the end of a spring. Solve for the value of k assuming that the restoring force acting on the system takes the same form as Hooke's law), b) the time period of its simple harmonic motion c) the frequency of the simple harmonic motion.

When the door is open and at rest, the door closer exerts a torque of 5.6 N*m. What is the moment of inertia of the door? If you let go of the open door, what is its angular acceleration immediately afterward?
