Because the liver helps to regulate blood clotting, people<span> with liver disease (for example, hepatitis or cirrhosis) also have a tendency to </span>bleed<span> easily. Most commonly, easy or excessive bruising occurs because the skin and blood vessels are fragile.

When two forces act in the same direction, they add together. ... Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
 
        
             
        
        
        
The problem is solved and the questions are answered below.
Explanation:
a. To calculate the speed of the 0.66 kg ball just before the collision
V₀ + K₀ = V₁ + K₁
= mgh₀ = 1/2 mv₁²
where, h= r - r cosθ
 V = 
  V = 2.42 m/s
b. Calculate the speed  of the 0.22 kg ball immediately after the collision
y = y₀ + Vy₀t - 1/2 gt²
 0 = 1.2 - 1/2 gt²
 t = 0.495 s
x = x₀ + Vx₀t 
1.4 = 0 + vx₀ (0.495)
Vx₀ = 2.83 m/s
C. To Calculate the speed of the 0.66 kg ball immediately after the collision
m₁ v₁ = m₁ v₃ + m₂ v₄
(0.66)(2.42) = (0.66) v₃ + (0.22)(2.83)
V₃ = 1.48 m/s
D. To Indicate the direction of motion of the 0.66 kg ball immediately after the collision is to the right.
E. To Calculate the height to which the 0.66 kg ball rises after the collision
 V₀ + k₀ = V₁ + k₁
1/2 mv₀² = mgh₁
 h₁ = v₀²/2 g
   = 0.112 m
F. Based on your data, No the collision is not elastic.
Δk = 1/2 m₁v₃² =1/2 m₂v₄² - 1/2 m₁v₁²
      = 1/2 (0.66)(1.48)² + 1/2 (0.22)(2.83)² - 1/2 (0.66)(2.42)²
      = - 0.329 J
Hence, kinetic energy is not conserved.
