i need help with question 13.25...please
The bungee jumper, an 80kg man, falls from the bridge at A with the bungee cord secured to his ankles, as shown in figure 1. He falls 20m before the 17m length of the elastic bungee cord begins to stretch. The 3m of rope above the elastic cord has no appreciable stretch. The man is observed to drop a total of 44m before being pr ...continues

FIND MASS MOMENT OF INERTIA OF THE PULLEY GIVEN ANGULAR ACCELERATION AND VELOCITY.
I CANNOT SEEM TO FIND THE ANSWER TO THIS PROBLEM ANYWHERE. I TRIED JUST SETTING IT EQUAL TO THE MOMENT ABOUT THE CENTER, BUT THAT SEEMS TO EASY. (See attached file for full problem description)

Relative Acceleration Problem, one ar along a straight line and the other along a curved path.
One of the toughest problem in Dynamics. Problem– At the instant shown, car A has a speed of 20 km/h, which is being increased at the rate of 300 km/h2 as the car enters an expressway. At the same instant, car B is decelerating at 250 km/h2 while traveling forward at 100 km/h. Determine the velocity and acceleration of A ...continues
A tricky string pulley problem in dynamics.
A tricky string_pulley problem. Problem # 2 – If the end of the cable at A is pulled down with a speed of 2 m/s, determine the speed at Which block B rises. Give logical explanation i.e. qualitative as well as quantitative way. For figure, please see attached file.
See attached file for full problem description. Please use energy approach. T1+W1-2=T2, T1=0, T= ½ ( m x V ²). T= T gear + T bar+ T collar, T collar = T bar=0.
