Question

If you free fall for 2.6 seconds what will be your final velocity and how far will you fall?

Answer 1

Your internal velocity will be 0, and acceleration will be 9.81 as default, and negative because it's falling down.
Using this equation to solve for final velocity:
Vf = a*t + Vi
Vf = -9.81*2.6 + 0
Vf = 25.51 m/s
To find your displacement, use this equation
Displacement=1/2*a*(t)^2 + Vi*t
D= 1/2*-9.81*6.76+0
D= -33.16 m
Displacement is negative because you free fall.
