Question

a car is moving with velocity 40 meter per second acceleration is 2 metre second square and the time is 20 sec so find final velocity of a car​

Answer 1

given: a=2m/s^2

u=40m/s

t=20sec

v=?

a = v+u/t

2=v+40/20

2×20=v+40

40=v+40

v=40-40

v=0m/s

please follow me

Answer 2

Answer:

V=80m/s

Explanation:

u = 40m/s

v = ?

a = 2m/s^2

t = 20s

Formula - v=u+at

v=40+2(20)

v=80m/s
