Easy

Solution

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).
