Answer:

a = 2.5 m/s²

Explanation:

given,

initial speed = 0 m/s

final speed = 25 m/s

time = 10 s

acceleration of bike is equal to change in velocity per unit time

  [tex]a = \dfrac{\Delta v}{t}[/tex]

  [tex]a = \dfrac{v_f-v_i}{t}[/tex]

  [tex]a = \dfrac{25-0}{10}[/tex]

         a = 2.5 m/s²

hence, acceleration of bike is equal to a = 2.5 m/s²
