Final answer:
Upton Chuck's final velocity after free falling for 4.2 seconds is calculated using the formula for velocity in free fall (v = gt), which yields a calculated and rounded value of 41.2 m/s.
Step-by-step explanation:
To determine Upton Chuck's final velocity after free falling for 4.2 seconds, we can use the formula for the velocity of an object in free fall:
v = gt
Where v is the final velocity, g is the acceleration due to gravity (9.8 m/s² on Earth), and t is the time in seconds.
Using this formula for Upton's situation:
v = (9.8 m/s²) × (4.2 s) = 41.16 m/s
After rounding to one decimal place, Upton's final velocity is 41.2 m/s.
