What is the gravity of a location if the mass of an object is 300 kg and it has a weight of 450N ?
kozerog [31]

The gravity is 1.5m\s^2

Further explanation:

The weight of any object is given by the product of mass and gravity of the object

Let

m denote the mass of object

g be the gravity

and

w be the weight

Then the statement can be mathematically written as:

w=m*g

Given

m=300kg

w=450N

Putting the values of m and w into the formula

450=g*300\\g= \frac{450}{300}\\g=1.5\ ms^{-2}

The gravity is 1.5m\s^2

Keywords: Mass, Gravity
