72% full it is 37,425.6 litres
height is (51980 / 1000) / 7.1 = 7.3
(i'm not sure if i am doing this right)
i know that pressure= force/area and that density = mass/volume i just don't know how to apply it to the problem
1. A train accelerates from rest at a constant rate and reaches a velocity of 153 kmh in a distance of 2.29 km. Calculate the acceleration and time taken.
If the breaks are then applied and produce a constant deceleration bringing the train to rest in a time of 140s, calculate the rate of...
