Question

If an object accelerates from rest, with a constant acceleration of 4.4 m/s2, what will its velocity be after 28s?

Answer 1

123.2 m/s after 28s

Step-by-step explanation:

Vi= 0 m/s

a= 4.4 m/s^2

t=28s

Vf after 28s

To find Vf use your kinematics formula Vf=Vi+at

Vi is Zero so it gets removed and the equation becomes

Vf=at

Simply Plug and Solve

Vf= 4.4(28)

Vf=123.2 m/s after 28s
