Gayle runs at a speed of 4.00 m/s and dives on a sled, initially atrest on the top of a frictionless, snow-covered hill. aftershe has descended a vertical distance of 5.00m, her brother, who isinitially at rest, hops on her back, and they continue down thehill together.
gayle's mass is 50.0kg, the sled's mass is 5.00kg and her brotherhas a mass of 30.0kg.

what is their speed at the bottom of the hill if the total verticaldrop is 15.0m?

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 = 2.6 m below the tank bottom which is a = 6.7 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). report your answer in meters to two decimal places.
