This works best using a tap outside which is raised off the ground a height unless you have a deep sink. you can also use a hose raised above the ground (without a nozzle). turn on the water so that the water is running smoothly (turned on a small amount). 1. describe what you see with respect to the diameter of the water near the tap and near the ground/sink surface. 2. explain in terms of continuity theorem and bernoulli's equation what is happening.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
