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

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]

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
