Question

An object with a mass of 40 kg is acted on by a net force of 680 N.
Determine the acceleration of the object.

Answer 1

Answer:

The acceleration of the object is $17\ m/s^2$

Explanation:

Force

Newton's second law states the net force exerted by an external agent on an object of mass m is:

F=m.a

Where a is the acceleration produced on the object.  The acceleration can be calculated by solving for a:

$\displaystyle a=\frac{F}{m}$

We have an object with a mass of m=40 kg that is acted on by a net force of F=680 N.

Calculate the acceleration:

$\displaystyle a=\frac{680\ N}{40\ kg}$

Calculating:

$a = 17\ m/s^2$

The acceleration of the object is $17\ m/s^2$
