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

  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:\(4m/s^2\)

Explanation:

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

\(F=20N\)

and

\(m=5kg\)

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

\(F=ma\)

Where \(F\) is the force acting on the object, \(m\) is the mass of the object and \(a\) is the acceleration.

Since we need \(a\) we clear for it in the equation:

\(a=\frac{F}{m}\)

And finally, we replace the values we already know:

\(a=\frac{20N}{5kg} =4m/s^2\)

The acceleration of the object is \(4m/s^2\)
