Question

a car moving at a velocity of 25 m/s, accelerates at arate of 6 m/s2. find its velocity after 3s

Answer 1

Answer:

Explanation

u = 25m/s

a = 6m/s²

t = 3s

v = u + at

⇒ v = 25 + 6×3

⇒ v = 25+18

⇒ v = 43 m/s

Answer 2

Answer:

43 m/s

Explanation:

a= vf-vi/t

6=vf-25/3

6*3=vf-25

18=vf-25

vf=18+25

vf=43 m/s
