How Does Gravity on Planet Zircon Compare to Earth?

Click For Summary

Homework Help Overview

The discussion revolves around determining the acceleration due to gravity on the fictional planet Zircon based on the motion of a rock tossed horizontally by an astronaut. The problem involves analyzing the horizontal and vertical components of the rock's motion.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to identify relevant variables such as initial velocity and distances involved. Some are considering how to calculate time based on the given distances, while others are questioning how to relate these to the acceleration due to gravity.

Discussion Status

There are multiple lines of reasoning being explored, with some participants suggesting formulas and relationships that could be used to find time and subsequently the acceleration. However, there is no explicit consensus on the approach to take, and some participants express uncertainty about how to proceed.

Contextual Notes

Participants are working with the assumption that the motion can be analyzed using kinematic equations, but there is a lack of clarity on how to apply these to the specific context of Zircon. The original poster expresses confusion about how to start the problem, indicating potential gaps in understanding the setup.

An astronaut on the planet Zircon tosses a rock horizontally with a speed of 6.55 m/s . The rock falls through a vertical distance of 1.20 m and lands a horizontal distance of 8.60 m from the astronaut. What is the acceleration of gravity on zicron?

I have no idea how to even start.
 
Physics news on Phys.org


i think x may be 8.60
 


okay so what I am thinking is that the Vinitial is 6.55 m/s and x=8.60 and form there I can find time
 


so I know I have to find time and then from there I can find acceleration but I don't know how to find time from what is given..?

On Earth it's

y = 1/2*g*t2

The time can be determined from

d/v = t

So on Zircon ...

1.2m = 1/2*Z*(d/v)2

or Z = 2*1.2*(v/d)2
