a = 4
v= u + at
as it started from rest so u = 0
v = at
t= 5
v= 4*5
v= 20 m/ sec
v= u + at
as it started from rest so u = 0
v = at
t= 5
v= 4*5
v= 20 m/ sec

acceleration = velocity/time
velocity = acceleration × time
velocity = 4 × 5
velocity =20m/s
velocity = acceleration × time
velocity = 4 × 5
velocity =20m/s
