A particle starts from the rest, moves with constant acceleration for 15s. If it covers `s_1` distance in first 5s then distance `s_2` in next 10s, then find the relation between `s_1 & s_2`.

Explanation

To solve the problem step by step, we will use the equations of motion under constant acceleration.

### Step 1: Identify the initial conditions
The particle starts from rest, which means:
- Initial velocity (u) = 0 m/s
- Acceleration (a) = constant
- Total time of motion = 15 seconds
