The $x$ and $y$ coordinates of the particle at any time are $x = 5 t - 2 t^{2}$ and $y = 10 t$ respectively, where $x$ and $y$ are in meters and $t$ in seconds. The acceleration of the particle at $t = 2 s$ is:
$0$
$5 m / s^{2}$
$- 4 m / s^{2}$
$- 8 m / s^{2}$

$x = 5 t - 2 t^{2}$
$y = 10 t$
$\frac{d x}{d t} = 5 - 4 t$
$a_{x} = \frac{d^{2} x}{d t^{2}} = - 4$
$a_{y} = \frac{d^{2} y}{d t^{2}} = 0$
$a = a_{x} + a_{y} = - 4 + 0$
$a = - 4 m s^{2}$

The x and y coordinates of the particle at any time are x=5t−2t2 and y=10t respectively, where x and y are in meters and t in seconds. The acceleration of the particle at t=2 s is:05 m/s2−4 m/s2−8 m/s2

The $x$ and $y$ coordinates of the particle at any time are $x = 5 t - 2 t^{2}$ and $y = 10 t$ respectively, where $x$ and $y$ are in meters and $t$ in seconds. The acceleration of the particle at $t = 2 s$ is:
$0$
$5 m / s^{2}$
$- 4 m / s^{2}$
$- 8 m / s^{2}$

$x = 5 t - 2 t^{2}$
$y = 10 t$
$\frac{d x}{d t} = 5 - 4 t$
$a_{x} = \frac{d^{2} x}{d t^{2}} = - 4$
$a_{y} = \frac{d^{2} y}{d t^{2}} = 0$
$a = a_{x} + a_{y} = - 4 + 0$
$a = - 4 m s^{2}$
