Final answer:
The acceleration due to gravity on Mars is 3.71 m/s².
Step-by-step explanation:
The acceleration due to gravity on Mars is 3.71 m/s².
When a rock is thrown upward on Mars, the acceleration due to gravity is still 3.71 m/s² because it is a property of Mars itself and not influenced by the motion of the rock. This means that regardless of whether the rock is going up or coming down, the acceleration due to gravity remains the same.
