If a vehicle starts from rest and accelerates forward at4.5 m/s what will its final velocity be after 8s

Sagot :

Answer: Final velocity will be 36m/s

Explanation:  Given:- u=0 m/s.  t=8s

                                     a=4.5m/s

from 1st Identity of motion

v = u + at

=> v = 0 + (4.5)(8)

=> v = 0 + 36.0

=> v = 36m/s

Hence final velocity after 8s will be 36m/s
