Question

How fast Will a brick be going after it falls for 2.5 seconds?

Answer 1

Answer:

25 m/s

Explanation:

Initial Velocity = 0 m/s

Time = 2.5 m/s

Acceleration due to gravity = 9.8

Final Velocity = ?

By the formula,

                           $V_{f} = V_{i} + at$

                            $V_{f}= 0 + 10 x 2.5$

                            Vf = 25 m/s
