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 :
