An object located near the surface of Earth has a weight of a 245 N object?
• What is the mass of the object?
• What is the weight of the object on Mars where the gravity is
3.72 m/s?

Given the data in the question;

Weight of object;

Weight the measure of the force of gravity pulling down on a particle or object.

It is expressed as:

Where m is mass of the object and g is acceleration due to gravity { Acceleration due gravity of Earth }

We substitute our values into the equation

Therefore, mass of the object located near the Earth surface is 25kg

So on planet Mars; , we know that mass of the object is

We substitute into our equation

Therefore, the weight of the object on Mars with the given gravity is 93 Newtons.

The mass of the object is 24.5 kg and weight of the object on Mars is 91.14 N.

Explanation:

Weight of the object on the surface of Earth, W = 245 N

On the surface of Earth, acceleration due to gravity, g = 10 m/s²

Weight of an object is given by :

W = mg

m is mass

So, the mass of the object is 24.5 kg

Acceleration due to gravity on Mars, g' = 3.72 m/s²

Weight of the object on Mars,

W' =mg'

W' = 24.5 kg × 3.72 m/s²

= 91.14 N

So, the weight of the object on Mars is 91.14 N.

the total distance traveled by the car is

30km + 49km = 79 km .
