A string mounted on a package and is drawn at an of 30* above the horizontal with a pressure of G. May be the speed of this package just like in this condition when.. A straight bar is pressed up in to the back of a stop at 30* above the horizontal with exactly the same pressure P. I question this due to don't know if the Normal Force is lowered by the second situation or if it remains exactly the same. Thanks ahead of time. **block, number straight back
