1 | I am going to shoot a pellet... a metal ball. | |
2 | These steel ball bearings have a density of about 7,800 kilograms per cubic meter. | |
3 | So the first thing I want to do is to shoot it up vertically and how are you going to help me to calculate... to tell me how high it is? | |
4 | The front connector includes an inner cylinder, a steel ball, a loop, a spring and a collar. | |
5 | And what I calculated was the terminal velocity as a function of radius of these ball bearings. |
