Question

An astronaut is standing on a hot air balloon in a different planet when he accidentally drops a wrench. He observes that the gravitational acceleration on the this planet is $2.4m/s^2$. If he had thrown the wrench at an upward angle instead, he would have found the gravitational acceleration on this planet to be:

• A. less than $2.4m/s^2$
• B. toward him at $2.4m/s^2$
• C. downward at $2.4m/s^2$
• D. greater than $2.4m/s^2$
• E. none of these

Answer 1

Answer: (C)

downward at $2.4m/s^2$

When he throws the wrench at an upward angle , the gravitational acceleration will not be affected and will be $2.4m/s^2$ downwards. Throw of wrench is not affecting the factors on which gravitational acceleration depends.
