The Jupiter Rover has a mass of 300kg. If the acceleration due to gravity on Jupiters' surface is -2.15m/s^2.?what is the magnitude of the Rover's weight on Jupiter??

There is an error in the information provided. The acceleration due to gravity cannot be negative as the force of gravity between two bodies is an attractive force. I assume you meant the acceleration due to gravity is 2.15 m/ s^2.

A body's weight on a planet is the force with which it is attracted towards the surface of the planet. This is given as m*g, where m is the mass of the body and g is the acceleration due to gravity.

The mass of the Jupiter Rover is 300 kg and the acceleration due to gravity on the surface of Jupiter is 2.15 m/s^2

This gives the weight of the Jupiter Rover on the planet as 300*2.15 = 645 N

weight is a type of force which depends on the mass of the object and the value for the acceleration due to gravity on a given planet.

The formula is:  F(w) = mg where m is the mass and g is the value for g.

In this case:

m= 300 kg

g = 2.15 m/s/s

Therefore:  F(w) = 300 * 2.15 = 645 Newtons.

Just a side note: the actual value of g for Jupiter is 22.88 m/s/s
