What is the gravitational force acting on a 54.0kg object on earth’s surface?

529.2N

Explanation:

Given parameters:

Mass of the object  = 54kg

Unknown:

Gravitational force acting on the mass  = ?

Solution:

To solve this problem, the gravitational force acting on this body is tantamount to the weight of the object.

         So;

    Weight  = mg

m is the mass

g is the acceleration due to gravity

    Now;

     Weight  = 54 x 9.8  = 529.2N

The gravitational force acting on the object is 529.2N

truck y has a greater velocity than truck x.
