The oxidation number of Pb is +2
Answer: Vo = 10.84 m/s
Explanation:
1) Data:
d = 3.95m
t = 1.75s
g = 9.81 m/s²
Vo = ?
2) Formula
Vertical motion ⇒ d = Vo×t - g×t² / 2
3) Solution
Clearing Vo, you get:
Vo = [ d + gt² / 2] / t
⇒ Vo = [ 3.95m + 9.81 m/s² (1.75s)² / 2 ] / 1.75s = [3.95m + 15.02m] / 1.75s
Vo = 18.97 m / 1.75s = 10.84 m/s
MgCl2 is Magnesium chloride
