At the surface of a certain planet, the gravitational acceleration g has a magnitude of 12.0 m/s2 . a 24.0-kg brass ball is transported to this planet. what is?

(a) the mass of the brass ball on the earth and on the planet, and
(b) the weight of the brass ball on the earth and on the planet?

The mass of the ball is 24kg both on the Earth and on that planet.

The weight on Earth is 240N and on that planet is 288N.

Explanation:

The mass of a body is the same everywhere but the weight of a body varies from place to place.

To calculate the weight on Earth:

g on earth=10m/s2

Weight = mass *g

W=24*10

=240N

To calculate the weight on the planet:

g on the planet=12.0m/s2

W=24*12

=288N

The mass does not change, so it would be 24.0 kg on earth and on the planet.

For the weight you use the eqaution w=mass*g

Explanation:

For the weight equation of earth take w=24kg*9.8m/s^2 (answer is in kg)

for the planet use w=24kg*12 m/s^2 (answer is in force, N)
