Two objects slide over a frictionless horizontal surface The first object, mass `m_(1)=5` kg, is propelled with a speed `u=4.5m//s` towards the second object, mass `m_(2)=2.5` kg while is intially at rest. After the collision, both objects have velocities which are directed at `theta=30^(@)` on either side of the original line of motion of the first object. What are the final speed of the two object? Is the collision elastic or inelastic?

Explanation

To solve the problem step by step, we will analyze the collision of the two objects using the principles of conservation of momentum and kinetic energy.

### Step 1: Understand the Problem
We have two objects:
- Object 1 (mass \( m_1 = 5 \, \text{kg} \)) moving with an initial speed \( u = 4.5 \, \text{m/s} \).
- Object 2 (mass \( m_2 = 2.5 \, \text{kg} \)) is initially at rest.

After the collision, both objects move at an angle \( \theta = 30^\circ \) to the original line of motion of object 1.
