Answer:

0.5m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Final velocity  = 5m/s

Time taken  = 10s

Unknown:

Acceleration of the bicycle  = ?

Solution:

Acceleration is the rate of change of velocity with time.

   Acceleration  = [tex]\frac{v - u}{t}[/tex]  

v is the final velocity

u is the initial velocity

t is the time taken

  Insert the parameters and solve;

     Acceleration = [tex]\frac{5-0}{10}[/tex]   = 0.5m/s²
