Question

Two spheres A and B of masses 500 gm and 750 gm are moving along the same line witt h velocity 5m/s and 3 m/s respectively. They collide and move away from each other.Sphere A moves with a velocity of 4 m/s. Determine the velocity of sphere B.

Answer 1

Answer:

Hey Buddy here is your Answer

v₂=11/3 m/s

Explanation:

u₁=5 m/s   u₂=3 m/s  m₁=500 g =0.5 Kg   m₂=750 g =0.75 Kg

v₁=4 m/s   v₂=?

            Using law of conservation of momentum

      m₁u₁+m₂u₂=m₁v₁+m₂v₂

⇒0.5x5 + 0.75x3=0.5x4 + 0.75xv₂

⇒2.5 + 2.25 = 2 + 0.75xv₂

⇒2.75=0.75xv₂

v₂=275/75=11/3 m/s
