What is the weight of an object(mass = 60 kilograms) on mars, where the acceleration due to gravity is 3.75 meters/seconds?

The weight of ANY object located ANYwhere is the product of

(the object's mass) times (the gravity at that place).

If the acceleration of gravity happens to be 3.75 m/s², then

Weight = (mass) x (3.75 m/s²)

Weight = (60 kg) x (3.75 m/s²)

Weight = 225 Newtons . (about 50.6 pounds)

The same 60-kg object would weigh 588 N (about 132 pounds)
on Earth, and 97 N (about 22 pounds) on the moon. 

If an object is moving or in motion

It may possibly be c i think |-/
