i) Two objects, each of mass 2.5 kg are moving in the same straight line but in opposite
directions. The velocity of each object is 4.5 m s−1
before the collision during which they stick
together. What will be the velocity of the combined object after collision?

Answer:

Here is your required answer

Explanation:

Given,

Two objects of mass 2.5kg

m₁ = m₂ = 2.5kg

Initial Velocity

U₁ = U₂ = 4.5 ms⁻¹

Then total mass of combined system,

M = m₁ + m₂

   = 2.5 + 2.5

   = 5 kg

Let the velocity of the combined system after the collision be v

Let us apply Law of Conservation of Linear Momentum,

m_1u_1 -m_2u_2 = MV

2.5 × 4.5 - 2.5 × 4.5 = 5 × V

0/5 = V

V = 0 ms⁻¹

Hence the velocity of combined object after the collision will be 0 m/s

Hope it helps you
