The initial speed of each block is v0 = 6.92 m/s, and each incline slopes upward at an angle of θ = 50.0°. the block on the shorter track leaves the track at a height of h1 = 1.25 m above the ground. find (a) the height h for the block on the longer track and (b) the total height h1 + h2 for the block on the shorter track.

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
