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 1s later,
b 5s later?​

Answer 1

$\huge\bold\red{ANSWER}$

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
