Question

if u=4m/s a=8m/s2 t=sec then what is final velocity​

Answer 1

Bro you haven't given time...

Use the formula given below, put the value  of t and you'll get the answer

v= u+at

u=4m/s

a=8m/s2

v= 4 + 8t

Answer 2

$\huge\boxed{\underline{\underline{\green{\tt Solution}}}} </p><p>$

Initial Velocity = u = 4

Acceleration = a = 8

Time = t =2

We know that

Final Velocity

$= u \: + at$

$= 4 + 8 \times 2 = 20$

Hence the Final Velocity = 20m/s
