What is the force exerted on an object with a mass of 20 kg and an acceleration of 6 m/s2?

OverLord2011 [107]

Answer:

F = 120 N

Step-by-step explanation:

Given that,

The mass of the object, m = 20 kg

Acceleration of the object, a = 6 m/s²

We need to find the force exerted on an object. The force exerted on an object is given by :

$F=ma\\\\F=20\ kg\times 6\ m/s^2\\\\F=120\ N$

So, the required force exerted on the object is 120 N.
