Describe a ball's motion as it rolls up a slanted
driveway. It starts with an initial velocity of 1.25 m/s up the ramp. It
travels upward, while slowing down, for 4.22 s, stops for an instant,
and then rolls back down. What are the direction and the magnitude
of the ball's acceleration as it rolls up the driveway?

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)
