Somebody please help me with this science question

50 Kg.

Explanation:

The following data were obtained from the question:

Force (F) exerted = 1000 N

Acceleration (a) = 20 m/s²

Mass (m) of object =?

Force (F) is simply defined as the product of mass (m) and acceleration (a). Mathematically, it is expressed as:

Force (F) = mass (m) × acceleration (a)

F = ma

With the above formula, we can obtain the mass of the object as illustrated below:

Force (F) exerted = 1000 N

Acceleration (a) = 20 m/s²

Mass (m) of object =?

F = ma

1000 = m × 20

Divide both side by 20

m = 1000/20

m = 50 Kg

Thus, the mass of the object is 50 Kg
