Answer:

[tex]\huge\boxed{\sf V_f=45.2 \ m/s}[/tex]

Explanation:

Given Data:

Initial velocity = [tex]V_i[/tex] = 6 m/s

Time = t = 4 sec

Acceleration due to gravity = g = 9.8 m/s²

Required:

Final velocity = [tex]V_f[/tex] = ?

Formula:

[tex]v_f=v_i+gt[/tex]

Solution:

Put the givens in the formula

[tex]V_f=6 +(9.8)(4)\\\\V_f=6+39.2\\\\V_f=45.2 \ m/s\\\\\rule[225]{225}{2}[/tex]
