You throw a baseball from the roof of a house to a friend on the ground. The ball has an
initial velocity of 12.0 m/s in the horizontal direction. After 1.00 s, how fast is the ball
moving in (a) the x direction and (b) the y direction. A) the velocity in the x-direction
doesn't change. Therefore, after 1.00 seconds we have

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.
