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 deceleration
2. A vertical cylindrical chemical process tank has a diameter of 3m. the tank has a capacity when full, of 51980 litres. if the tank is filled to 72% of its maximum capacity with a mixture of liquids with a combined density of 1063 kg/m3 determine the pressure at the base of the tank
