Answer 2

hey user,

initial velocity (u) = 0 m/s

final velocity (v) = 20m/s

time = 2s

acceleration (a)=?

distance (s) = ?

firstly,

acceleration = v - u /t

= 20 -0/2

= 20/2

= 10 m/s².

now,

by putting the formula,

S = ut + 1/2at²

S = 0×2 + 1/2×10×2²

S = 0 + 10×2

S = 20m....

$\huge \tt \red{answer \: = \: 20m}$
