A vehicle moving with a uniform acceleration of 2 m / s2 has a velocity of 4 m / s at a certain time. What will its velocity be 2 s later?

Answer :

karthik4297
Acceleration of a vehicle (a) = 2 m/s²
Initial velocity(u) = 4 m/s
time interval (t) = 2 second 
We know that , 
                 v = u + at
                 v = 4 + 2×2 = 8 m/s 
Therefore the velocity of vehicle after(when it's velocity was 4 m/s)  2 sec = 8 m/s

a=2m/s2   u=4m/s    v  at t=2s then v=4 +2x2=8m/s
