Answer:
the speed of the snow ball after collision is equal to 3 m/s
Explanation:
given,
mass of the two balls
m₁ = 0.4 Kg
m₂ = 0.6 Kg
initial velocity of each ball = v₁ = 15 m/s
Speed of 1 Kg mass after collision = ?
using conservation of momentum
m₁ v₁ - m₂ v₁ = (m₁+m₂) V
negative velocity shows that second ball is moving in opposite direction.
0.4 x 15 - 0.6 x 15 = (1) V
V = - 3 m/s
Hence,
the speed of the snow ball after collision is equal to 3 m/s
After collision, the speed of snow will be "3 m/s".
Whenever two things come into interacting directly with one another, this is referred to be a collision. It should be the process through which two or more substances generate pressures on each other throughout a relatively brief period of duration.
According to the question,
Mass of two balls, m₁ = 0.4 kg
m₂ = 0.6 kg
Initial velocity, v₁ = 15 m/s
By using Conservation of momentum,
→ m₁v₁ - m₂v₂ = (m₁+m₂)V
By substituting the values, we get
0.4 × 15 - 0.6 × 15 = 1 × V
6 - 9 = V
V = -3 or,
V = 3 m/s
Thus the above response is correct.
