Final answer:
To find the mass of a robot on Venus with a weight of 180 N and gravity of 8.9 m/s², the formula m = w/g can be used, resulting in a mass of approximately 20 kg.
Step-by-step explanation:
The student asked how to calculate the mass of a robot on Venus given that the gravity there is 8.9 m/s² and its weight is 180 N. The formula to find the mass (m) when the weight (w) and acceleration due to gravity (g) are known is w = mg. By rearranging the formula to solve for mass, we get m = w/g.
Using the values provided:
m = 180 N / 8.9 m/s²
m = 20.2247191 kg
However, as answers need to be rounded to the closest whole number, the mass of the robot on Venus is 20 kg.
