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]
