I didn't understand your notation there, why is there a 100 and a 125 on separate lines? And what symbol is supposed to go between 275 and 246 to get 541.2?boss302 said:your right it is pritty easy actually firstly with a max power of 300 and a efficiency of 82% you need to find the "real power" 300 x 82 = 246kw
100
now finding the max velocity of the plane 275 x 246 = 541.2
125
as the plane is travelling 275kmh to the left it is left with 541.2-275 = 266.2kmh it can use this velovity in the up direction. this drawing a force triangle it has 275 to the left and 266.2 up. then both the angle and resultant can be found( angle = 44 resultant = 383kmh
