Bungee Jump Simulation (Second order Ordinary Differential Equations) A team of engineering students is planning a bungee jumping trip. One of the preparation tasks is to write a MATLAB program to simulate high-altitude bungee jumping using a 150-meter bungee line. The purpose of the simulation is to estimate the peak acceleration, velocity, and drop distance of the jump to ensure that the arresting force of the bungee is not too great and the jump off point is high enough so that no one will hit the ground. The equation to use for the analysis is Newton's Second Law, F = ma where F is the sum of the gravitational, aerodynamic drag, and bungee forces acting on the jumper, m is the mass of the jumper (which is 70 kg), and a is the acceleration. Define the distance the jumper falls as the variable x (which is a function of time, x(t)). The jumper's velocity and acceleration are then represented as x' and x", respectively. The Newton's equation to solve for acceleration: x" = F/m Next,…

Find the acceleration of the specified object. (Hint: Recall that if a variable is changing at a constant rate, its acceleration is zero.) A boat is pulled into a dock by means of a winch 2 meters above the deck of the boat (see figure). The winch pulls in rope at a rate of 1.7 meters per second. Find the acceleration (in m/sec?) of the boat when there is a total of 5.2 meters of rope out. (Round your answer to three decimal places.) m/sec2 Not drawn to scale Submit Answer

The velocity of A is 1.7 m/s downward, the velocity of B is 2.6 m/s upward, and the velocity of D is 3.1 m/s downward. Find the velocity of C. The velocity of C is positive if downward, negative if upward. D B Answer: vc= i C ! m/s

Relative Motion Analysis using Rotating Axes, use the formulas attached to find the solution to the problem, in addition you can use Relative motion using translating axes to find velocity and acceleration of D and E, but to find the velocity of C you must use the rotating axis formula given, the formula given is a general formula. State which where the axis XYZ and xyz will be. Solve in vector form.
