EasySolution
Option B is the correct answer.
Option Analysis
Question is asking about approximate value v = √(2(9.8))m/0.5j
Substitute given m = 96, and j = 49
v = √(2(9.8))*96/(0.5*49)
v = √((19.6)*96)/(24.5)
v ≈ √((16)*100)/(25) (Just approximate to nearest perfect square)
v ≈ √(40/5) v ≈ 8
So the closest answer is B(9).
