Please Help! Range of a horizontally launched projectile is given by: R= Vx,
g
Explain how you can graphically obtain launch height H, by plotting R vs. Vg.
Use this graph to calculate H and compare it with known value of 10 m.
(Paste the graph with linear fit here.)

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.
