Question

(b) Consider an object of speed v and constant mass which undergoes energy transfer. Assuming all quantities are defined with respect to the object, write down which one of the following would not be possible: (A) due to air resistance (drag), W 2 J (B) ДЕ,--10 J (C) final Ep10J (D) if Q- -W the energy of the object remains constant (E) Ek increases by factor 2 (doubles) and v increases by factor V2 (c) During 1 cycle, a heat engine loses 30 J as heat output, gains 25 J as work input, loses 35 J as work output. Find the efficiency as a percentage, assuming no change in kinetic or potential energy.Can someone please provide me a reasonable explanation to these two problems ( clear hand writing please + clear solution to them ).
