Q2 ) Starting from rest on a level road a girl can reach a speed of 5m/s in 10 s on her bicycle, find A) the acceleration

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  =  

v is the final velocity

u is the initial velocity

t is the time taken

  Insert the parameters and solve;

     Acceleration =   = 0.5m/s²

more than, less

less than, more
