Question

a partical starts from rest with accelaration 2.0m/s square what is the velocity of the partical at the end of 6seconds

Answer 1

v=u+at
v=0+2(6)
v= 12m/s after 6 seconds

Answer 2

Hello !
__________________________________________________________
u = 0 m/s 
a = 2m/s²
t = 6 seconds 
v = ?
__________________________________________________________
v = u + at 

v = 0 + 2 x 6 

v = 12 m/s
