1) In each of the following scenarios, based on the plane of impact (shown with an (n, t)) and the
motion of mass 1, draw the direction of motion of mass 2 after the impact. Note that in all
scenarios, mass 2 is initially at rest. What can you say about the nature of the motion of mass 2
regardless of the scenario?

respectively. The masses hit each other and have a coefficient of restitution e. After the impact,
mass 1 and 2 head to their respective gaps at angles a and ẞ, respectively. Derive expressions

- The fallowing question is from a reeds book on applied heat i am studying. Although the answer is provided, im struggling to understand the whole answer and the formulas and the steps theyre using. Also where some ov the values such as Hg and Hf come from in part i for example. Please explain step per step in detail thanks In an NH, refrigerator, the ammonia leaves the evaporatorand enters the cornpressor as dry saturated vapour at 2.68 bar,it leaves the compressor and enters the condenser at 8.57 bar with50" of superheat. it is condensed at constant pressure and leavesthe condenser as saturated liquid. If the rate of flow of the refrigerantthrough the circuit is 0.45 kglmin calculate (i) the compressorpower, (ii) the heat rejected to the condenser cooling water in kJ/s,an (iii) the refrigerating effect in kJ/s.
