Questions

Fоr the exаct mаtch questiоns #5 аnd #7, if yоu want to be considered for partial credit in the event your answer is incorrect, and you are not using a digital calculator, show your scratch work or your calculator up to the webcam for me to review.   You are an astronaut visiting an Earth-like exoplanet. How cool?! As we will learn in Unit 3, Earth-like is a very general term and does not necessarily mean exactly like Earth.  You also love your family and friends and want to see them again.  If this planet's size is `r` times that of our own and `m` times more massive, what escape velocity (in units of km/s) does your rocket need to come back home?  Please read and follow my input directions below. Input Instructions: Look to the equation sheet for everything you need, and you may only use the values provided exactly as given for your calculation. Type your final numerical value rounded to the nearest one decimal place  For example, 105.578 km/s would be inputted as 105.6.  Do not include any letters, words, E, or scientific notation in your answer.  You must match my answer exactly for credit. If something prevents you from typing in your answer here, just manually write your answer following the same rounding directions into the bonus section at the end of the exam.
