Question

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 a 1 s later?

Answer 1

Answer:

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

hope this helps ya...
