A 2.5 kg collar is attached to a spring of spring constant `250 Nm^(-1)` . It slides without friction over a horizontal surface . It is displaced from its equilibrium position by 20 cm and releasd. Calculate the period of osciallation and the maximum speed.

Explanation

To solve the problem step by step, we will calculate the period of oscillation and the maximum speed of the collar attached to the spring.

### Step 1: Identify the given values
- Mass of the collar (m) = 2.5 kg
- Spring constant (k) = 250 N/m
- Displacement from equilibrium (x) = 20 cm = 0.2 m (convert to meters)

### Step 2: Calculate the period of oscillation
