<em />

Step-by-step explanation:

Given

$Mass = 53kg$

$Force = 1800N$

Required

Determine the acceleration

The relationship between force, mass and acceleration is:

$Force = Mass * Acceleration$

Substitute values for Force and Mass

$1800 = 53 * Acceleration$

Solve for Acceleration

$Acceleration = 1800/53$

$Acceleration = 33.9622641509$

$Acceleration = 33.96ms^{-2}$ <em>---- Approximated</em>
