a force of 20 n acts upon a 5 kg block, calculate acceleration of the object

Sagot :

1. Newton's Second Law tells us how to calculate the acceleration if we know the force and the mass.
  F = m a
We are interested in determining the acceleration, so we divide both sides of the equation by m to get F / m = a a = (20 N) / (5 kg) a = 4 N / kg = 4 (kg m /s2 ) / kg = 4 m / s 2

Answer:

the acceleration is:[tex]4m/s^2[/tex]

Explanation:

We have information about the force acting on an object and the mass of that object:

[tex]F=20N[/tex]

and

[tex]m=5kg[/tex]

Given these data, we can use Newton's second law:

[tex]F=ma[/tex]

Where [tex]F[/tex] is the force acting on the object, [tex]m[/tex] is the mass of the object and [tex]a[/tex] is the acceleration.

Since we need [tex]a[/tex] we clear for it in the equation:

[tex]a=\frac{F}{m}[/tex]

And finally, we replace the values we already know:

[tex]a=\frac{20N}{5kg} =4m/s^2[/tex]

The acceleration of the object is [tex]4m/s^2[/tex]
