Question

. What is the velocity of a free-

falling object after 5 seconds?
(Use 10 m/s2 for gravity.)

Answer 1

vf = 50 m/s

Step-by-step explanation:

The equation for this kinematic problem is:

vf = vi + at

We are given:

a = 10m/s^2

vi = 0m/s

t = 5 sec

vf = ?

Solve for final velocity:

vf = 0 + 10(5)

vf = 50 m/s
