Starting from a stationary position, Raja paddles his bicycle to attain a velocity of 4 \(m\)\(/\)\(s\) in 45 \(s\). Then he applies brakes such that the velocity of the bicycle comes down to 3 \(m\)\(/\)\(s\) in the next 5 \(s\). Calculate the acceleration of the bicycle in both the cases.
1. Acceleration (before applying brake) \(=\)
2. Acceleration (after applying brake) \(=\)
