If rolling mill is running at 10 meters per second and roller table after mill is running at 20 meters per second.
Before cutting of bar, it will move at 10 meters per second.
Before cutting, roller table is trying to pull the bar, but since bar is not cut, it will slip on roller.
After cutting, bar has to move with the speed of 20 meters per second on roller table.
How much time bar will take to reach to that speed?
Coiff of friction of roller is 0.5
Homework Equations
F = Mass x a.
