Question

The chart shows approximations of the acceleration due to gravity in meters per second squared (m/sec2) for the eight planets in our solar system. The weight of an object on a given planet can be found by using the formula W = mg, where W is the weight of the object measured in newtons, m is the mass of the object measured in kilograms, and g is the acceleration due to gravity on the planet measured in m/sec2. What is the weight, in newtons, of an object on Mercury with a mass of 90 kilograms?

A. 88.2 N
B. 361.8 N
C. 63.0 N
D. 882.0 N

Answer 1

The weight of the object as we have from mercury is 324 N

Acceleration due to gravity, denoted by the symbol g, represents the acceleration an object experiences due to the gravitational pull of a massive body, usually a planet or a celestial body. The actual acceleration due to gravity can vary slightly depending on location, altitude, and factors such as planet shape and density.

We know that;

weight = mass * acceleration due to gravity

W = mg

W = 90 Kg * 3.6 m/
`sec^2`

W = 324 N

We have the weight as 324 N
