The 25-pound ter- rier on mars weighs more.
The given parameters:
- Mass on Pluto, m = 100 lb = 45 kg
- Mass on Mars, m = 25 lb = 11.25 kg
How does gravity affect weight?
- The weight of an object in any Planet is directly proportional to the acceleration due to gravity of the planet.
The acceleration due to gravity on Pluto and Mars is calculated as follows;
- Pluto = 0.62 m/s²
- Mars = 3.72 m/s²
The weight of the objects on different planet;
- Pluto = 45 x 0.62 = 27.9 N
- Mars = 11.25 x 3.72 = 41.85 N
Thus, the 25-pound ter- rier on mars weighs more.
