Good Day

Problem:

An object falls from a high building ignoring its air resistance. What would its velocity be after 6 seconds of falling?

Note: initial velocity is   0 m/s

Given:

a (acceleration) = 9.8 m/s²

Vi (initial velocity) = 0 m/s

Vf (Final Velocity)  = ? unknown

t (time) = 6 seconds

Solution:

To solve this problem, we can use the formula a = (Vf-Vi) / t

To solve for Vf, we can used Vf = at + Vi

Vf = at + Vi

    = 9.8 m/s² ×  6 s + 0 m/s

   = 58.8 m/s

Answer:

The velocity after 6 seconds will  be 58.8 m/s
