The final speed of the green ball : 8.5 m/s
<h3>Further explanation</h3>
Given
mass of Croquet ball = 0.5 kg
v₁= 10 m/s
v₁'= 1.5 m/s
Required
the final speed
Solution
The law of conservation of momentum
m₁v₁ + m₂v₂ = m₁v₁ '+ m₂v₂' (1=red croquet ball, 2=green croquet ball)
v₂=0 (at rest)
Input the value :

Answer:
The answer to the question is letter a. 2
Explanation:
Write the formula of each compound
Calcium hydroxide = Ca(OH)₂
Nitric acid = HNO₃
Water = H₂O
Calcium nitrate = Ca(NO₃)₂
Chemical Reaction
Ca(OH)₂ + HNO₃ ⇒ Ca(NO₃)₂ + H₂O
Reactants Elements Products
1 Ca 1
1 N 2
3 H 2
5 O 7
Balanced Chemical Reaction
Ca(OH)₂ + 2HNO₃ ⇒ Ca(NO₃)₂ + 2H₂O
Reactants Elements Products
1 Ca 1
2 N 2
4 H 4
8 O 8
