Aball is pushed with an initial velocity of 4.0 m/s. the ball rolls down a hill with a constant acceleration of 1.6 m/s2. the ball reaches the bottom of the hill in 8.0 s. what is the ball's velocity at the bottom of the hill?

Alarge box of mass m is pulled across a horizontal frictionless surface by a horizontal rope with tension t. a small box of mass m sits on top of the large box. the coefficients of static and

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)
