John is riding Supreme Scream at Knotts. If John free falls for 3.6 seconds, what will be his final velocity? Write only the numerical answer rounded to 3 digits.

Vf = 35.28 m/s

Explanation:

The final velocity of John can easily be determined by applying first equation of motion:

Vf = Vi + at

where,

Vf = Final Velocity of John = ?

Vi = Initial Velocity of John = 0 m/s (Since Supreme Scream stops for a brief moment before coming down)

a = acceleration = g (for free fall motion) = acceleration due to gravity = 9.8 m/s²

t = time taken = 3.6 s

Therefore, using the respective values in equation, we get:

Vf = 0 m/s + (9.8 m/s²)(3.6 s)

Vf = 35.28 m/s
