Heavy rains have flooded your professor's basement to a depth of 6 cm. This basement is 12 m by 10 m in area. You have a hose of diameter 1.7 cm and can run the hose from the water in the basement to a level 2.3 m below the level of the basement floor, into a low low portion of the yard. When the hose is filled with water, it acts as a siphon and empties the basement.
a. What is the speed of the stream of water leaving the hose?
b. Approximately how long does it take to empty the basement?
An object attached to a horizontal spring is oscillating back and forth along a frictionless surface. The maximum speed of the object is 1.25m/s.
A sailboat is running along a straight course with the wind providing a constant force of 55 lb. The only other force acting on the boat is resistance as the boat moves through the water. The resisting force is numerically equal to five times the boa..
