First find the surplus, i.e. (234+97+191)-436=86. Now if you want to maximise the 'all three' section, you have to distribute these surplus 86 into this section.But if you add 1 to this region,you are taking care of surplus of 2. Similarly if 10 is added, surplus of 20...

h = 5.75 m, g = 9.81 m/s2 , θ = 30 degrees , sin(30) = 0.5 h= vₒ²•sin²α/2g, vₒ= ? vₒ = √ (h.2g)/(sin^2θ) vₒ = √ (5.75m . 2x9.81m/s2)/(0.5^2) = 21.24 m/s

An object is 6000 mi from the surface of a 4000 mi diameter planet. If the relative speed is 12000 mi/hr and the surface gravity of the planet is 12.9 ft/s^2, determine the impact velocity at the surface. Given answer: 15460 mi/hr Thanks in advance.
