Question

if a force of 20 newton is exerted on an object having mass 4 kg then calculate acceleration produced in it.​

Answer 1

Answer:

force=mass×accelaration

force=20 N

mass=4kg

acceleration=?

therefore acceleration=force÷mass

A=20÷4 =5m/s²

Answer 2

Answer:

The acceleration produced by a force of 20 N on an object having mass 4 kg is $5 m/s^{2}$.

Explanation:

A force is an external agent capable of altering a body's condition of rest or motion. It has a magnitude and a direction.

Force F = m × a

Where,

m = mass of the object

a = acceleration of the object

Given that:

Force F = 20 N

Mass m = 4 kg

F = m × a

20 = 4 × a

⇒a = 20 ÷ 4 = $5 m/s^{2}$

Therefore, the acceleration produced by a force of 20 N on an object having mass 4 kg is $5 m/s^{2}$.
