A body oscillates with S.H.M. according to the equation
`x(t) = (10 m) cos [(2pit + (pi)/(8))]`
Calculate displacement and velocity at t = 1 s.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Write down the equation of motion
The equation of motion for the body in simple harmonic motion (S.H.M) is given as:
\[ x(t) = 10 \cos \left(2\pi t + \frac{\pi}{8}\right) \]

### Step 2: Calculate displacement at \( t = 1 \) second
To find the displacement at \( t = 1 \) second, substitute \( t = 1 \) into the equation:
