Project 2 – Planetary Weights

Due: Thursday, June 9^th

Introduction

You may remember from high school science that while mass stays constant, your weight is actually dependent on your mass multiplied how strong the gravitational pull of the planet is.  So if you were to travel to different planets, your weight would change.  In your first programming project, you are asked to compute just how much someone would weigh on the other planets in our solar system.

Background Knowledge

Here is the table of relative gravitational strength as compared to earth:

Planet	Relative Strength
Mercury	0.38
Venus	0.91
Mars	0.38
Jupiter	2.54
Saturn	1.08
Uranus	0.91
Neptune	1.19
Pluto	0.06

What you need to do

Your task is to write a program which:

• Asks the user to input a weight
• Displays that weight scaled appropriately on each of the other 8 planets

Example

Welcome to the planetary weight converter!

Please enter the weight you’d like to convert: 100

Here is your weight on other planets:

Mercury     38 lbs

Venus       91 lbs

The Moon    16 lbs

Mars        38 lbs

Jupiter     254 lbs

Saturn      108 lbs

Uranus      91 lbs

Neptune     119 lbs

Pluto       6 lbs

Submission

Submission guidelines will be handed out next week separately.

Requirements/Advice/Hints

• Your program must compile and run on the unixs.cis.pitt.edu machines.
• Style, which we will be discussing shortly, will also be graded on, in addition to correctness.
• Don’t forget to have appropriate comments in your code.
• Start early in case you have any questions.
• Don’t forget that the TA can help you too.
• Do not collaborate with anyone other than me or the TA!
• Do not search for a solution on the web!
