Hi friend!!!
Given, u=0
a=4m/s²
t=4s
Now, we know that v=u+at
→v=0+4(4)
v=16m/s
I Hope this will help u ;)

Hey!
As the body is starting from rest means it's initial velocity will be 0.
So,
u = 0
a = 4m/s²
v = ?
t = 4 sec.
Here ,
→'u' represents initial velocity.
→'a' represents acceleration.
→'v' represents final velocity.
→'t' represents time.
We know that there are 3 equations of motion!
1) v = u + at
2) s = ut + 1/2 at²
3) v² = u² + 2as
And according to question we will use 1st equation of motion!!
v = 0 + 4(4)
v = 16m/s

pls
hey could you pls help me
oops! I am seriously sorry frnd!
wait I will see ur question!
another question is also there
A body is thrown upwards with some velocity. It returns to the same point after some
time. Draw its velocity time graph.
