here is your answer dear

i hope it help you

Answer 2

Step-by-step explanation:

Acceleration= (v - u)/ t

= (20-0)/4

= 20/4

= 5m/s²

v = 20m/s² , t = 4sec, u = 0m/s², a = 5m/s²

By using second equation

of motion,

s = ut + 1/2 at²

=> s = 0 × 4 + 1/2 × 5 × 4 × 4

=> s = 0 + 40

=> s = 40 m

Therefore acceleration is 5m/s² and distance covered in 4 sec is 40m.
