The x and y co-ordinates of a partilce at any time t are given by:
`x=7t+4t^(2)` and `y=5t`
The acceleration of the particle at 5s is:

Explanation

To find the acceleration of the particle at \( t = 5 \) seconds, we need to follow these steps:

### Step 1: Find the velocity in the x-direction
The x-coordinate of the particle is given by:
\[ x = 7t + 4t^2 \]
To find the velocity in the x-direction (\( v_x \)), we differentiate \( x \) with respect to \( t \):
...
