Variables we know:

t = 8 seconds

Vi = 0 m/s

g = -9.81

Δy = ?

Vf = ?

Equation we will be using to solve for Vf: Vf = Vi + gt

Steps to solve:

Vf = (0) + (-9.81)(8)

Vf = -78.48 m/s

Hope this helps!! :)

Answer:

78.4m/s

Explanation:

The following were obtained from

t = 8secs

g = +9.8m/s2 ( since Bubba is falling towards gravity

V =?

V = gt

V = 9.8 x 8

V = 78.4m/s

Bubba's speed after 8secs is 78.4m/s
