Solve the given problem:
Starting from a stationary position, Rahul paddles his bicycle to attain a velocity of 6 \(m\)\(/\)\(s\) in 30 \(s\). Then he applies brakes such that the velocity of the bicycle comes down to 2 \(m\)\(/\)\(s\) in the next 10 \(s\). Calculate the acceleration of the bicycle in both the cases.
1. Acceleration (before applying brake) \(=\)
2. Acceleration (after applying brake) \(=\)
Important!
Note: Enter your answer with 2 decimal digits.
