If v = √(2(9.8))m/0.5j),

m = 96, and j = 49,

which of the following most closely approximates the value of v?

Option A:

0

Option B:

9

Option C:

17

Option D:

25

Option E:

33

Option B is the correct answer.

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).
