QUESTION 2 At a location where gravity acceleration constant g =9.80 m/s2, a projectile returns to its original height after 5.9 seconds, during which time it travels 74.1 meters horizontally. If air resistance can be neglected, what was the projectile's initial speed: vo = (Note: For fill in blank, I have set the unit for the answer. So, you just need to provide a number - Please write your numerical answer with all digits and do not use scientific notation. If you are not sure about the number of significant figures, you can keep the number of figures as many as possible - You will not be punished for doing this.) m/s ?

On October 14, 2012, Felix Baumgartner became the first human being to break the soundbarrier while falling freely. He jumped from a capsule that was lofted by a balloon to analtitude of 127,852 ft (38.96 km). The speed of sound at that altitude is 690 mi/h.(a) Assuming that air friction (drag) is negligible at such altitudes, how far would he haveto fall to reach the speed of sound? (The approximation for the gravitational potentialenergy near the Earth’s surface, Ug ≈ mgy, is accurate to better than 1% even at suchaltitudes. Track units carefully, though!). Draw energy bar charts of your system atthe start of Felix’s jump and when he reaches the speed of sound to support youranswer.(b) Friction is not negligible, even at this altitude. Baumgartner actually reached thespeed of sound at an altitude of 109,731 ft (33.45 km). What fraction of the system’schange in gravitational energy was converted to thermal energy (mostly thermal energyin the air) by the time Baumgartner reached the…

One type of engine used in space travel is an ion thruster. These engines produce a low force that results in small acceleration changes. If an ion-thrust engine is used to apply 87 millinewtons [mN] of force on a satellite with a mass of 1.7 megagrams [Mg], what is the acceleration produced in units of meters per second squared [m/s2]?
