Answer :
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
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]
