Question

An object with a mass of 20 kg has a net force of 80 N acting on it. What is the acceleration of the object?

Answer 1

4 m/s^2

Step-by-step explanation:

F = ma

80N = (20kg)a

80N/(20kg) = (20kg)a/(20kg)

4 m/s^2 = a

Answer 2

4 m/s²

Step-by-step explanation:

The formula used here:

F = ma

F is force (80 N)

m is mass (20 kg)

a is acceleration

Since we need to calculate acceleration we will arrange the formula:

a = F ÷ m

Now substitute the values and solve

a = 80 ÷ 20

a = 4

The proper unit for this acceleration is m/s²

So the object accelerates at 4 m/s²
