During an initial period of 10$10$ seconds, a bicycle travels at a steady velocity of 10$10$ m/$/$s.$.$ 

 

 Then, during a final period of 5$5$ seconds, brakes are applied to the bicycle so that its speed is reduced with a constant acceleration of magnitude 0.4$0\mathrm{.}4$ m/$/$s².$2.$ 

 

The direction of motion of the bicycle is always East.

 

 ($($a)$)$ What is the velocity of the cycle at the end of the final period? 

 

 ($($b)$)$ What distance does the bicycle travel during the initial period of 10$10$ s?$?$ 

  

 ($($c)$)$ What distance does the bicycle travel during the final period of 5$5$ s
