Question

An unbalanced force of 500 N is applied to a 75 kg object. What is the acceleration of the object?

Answer 1

Answer:

Acceleration, $a=6.66\ m/s^2$

Explanation:

Given that,

Force acting on the object, F = 500 N

Mass of the object, m = 75 kg

We need to find the acceleration of the object. The force acting on the object is given by :

$a=\dfrac{F}{m}$

$a=\dfrac{500\ N}{75\ kg}$

$a=6.66\ m/s^2$

So, the acceleration of the object is $6.66\ m/s^2$. Hence, this is the required solution.

Answer 2

1. Define Newtons second law of motion (this will help put things into perspective)

2.Get the mass of the object (in this case 75 kg)

3.The net force acting on the object...find it (in this case 500 N)

4.Change the equation to F=ma (500=75a)

5.Divide both sides by 75 and that is the acceleration.
