✔ 最佳答案
根據九江橋的專家調查組調查該橋設計時防撞力的設定, 非航行橋墩是40T (40000KG), 航行橋墩是1200T(1,200,000kg). 運砂船是撞倒非航行橋墩. 所以可以肯定當時的沖力遠大於40T的力度.

First, this is a momentum's question.
You should give me the mass.the first speed and the final speed and the collision time.
By the about information. You can use this equation mv-mu/t

正常橋墩設計能夠承受兩架大型貨車撞擊
沙船撞擊力加上汛期河水嘅沖擊力應該超過大橋設計
