A mass is fired from the top of a tower (point A) as shown in figure. If the initial speed vo-5m/s and the times does it take the mass to reach point B and point Care TB=2s and tc=4.5s, respectively, determine a) the components of the velocity at point B (VXB=? and VyB= ?), b) the distance at which the mass strikes the ground (xc=?), and c) the height of the tower (hA-YA - Yc?). y Ув A Ih A

this cylinder has a rod inside, around the rod there is paraffin wax that will expand, I want to know how to reduce the thickness of this cylinder. However, I don't know what formulas I need to be able to do this and how to do the calculations. Please can you make an example with the data you choose to have an example of how to do this step by step? Thank you Also keep in mind that the wax is expanding by an induction coil, and the heat is happening around the cylinder. And the thickness of the stainless steel cylinder has to be thin but not so thin that it causes a pressure problem.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
