A hot-air balloon is rising vertically at a constant speed of 15.0 ms-1. A sand bag is released from rest relative to the balloon when the balloon is 35 m above the ground. Calculate the maximum height of the object above the ground. Calculate the time taken to reach the maximum height. Calculate the total time taken for the object to reach the ground.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
