Answer:
The weight of an object is a measure of the force of gravity on the object. It is calculated by multiplying the mass of the object by the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 meters per second squared (m/s^2).
Therefore, to calculate the weight of the Mars rover Spirit on Earth, we can use the formula:
weight = mass * acceleration due to gravity
In this case, the mass of the Mars rover is 836 kg, and the acceleration due to gravity on Earth is 9.8 m/s^2. Plugging these values into the formula, we get:
weight = 836 kg * 9.8 m/s^2
This simplifies to:
weight = 8194.8 kg*m/s^2
The weight of the Mars rover Spirit on Earth is approximately 8195 kg*m/s^2.
