The net force on an object is 80 N. The mass of the object is 40 kg.
Art [367]

Answer:

The acceleration of object is 2 m.s⁻².

Explanation:

Given data:

Force on object = 80N

Mass of object = 40 kg

Acceleration = ?

Definition:

The acceleration is rate of change of velocity of an object with respect to time.

Formula:

a = Δv/Δt

a = acceleration

Δv = change in velocity

Δt = change in time

Units:

The unit of acceleration is m.s⁻².

Acceleration can also be determine through following formula,

F = m × a

a = F/m

Now we will put the values in formula.

a = 80 N/40 kg

a = 2 m.s⁻²  (N = Kgm.s⁻² )
