Andrej [43]

Answer:

<h2>16.59 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{68000}{4100}  =  \frac{680}{41}  \\  = 16.58536

We have the final answer as

<h3>16.59 m/s²</h3>
