Rev. May. 2018 WCLN.ca 4. What is the velocity of the water at the peak of the stream (the top)? What is it's acceleration at this point? 5 . Sketch a diagram (or, better yet, take a photo) and label all variables to be used in calculating the initial velocity (known as the "muzzle velocity"). Diagram: Label all variables used in calculations directly onto the diagram: Define variables: 6. Use this information to determine the initial speed at which the water exits the hose. Show all work below. Initial speed of water exiting the hose: Show all work. m/s
