Answer:
It will take 27 seconds for a cyclist to stop completely.
Explanation:
Initial velocity of the cyclist= u = 13.5 m/s
Acceleration of the driver = a =
Final velocity of the cyclist = v = 0
Duration of time in which 13.5 m/s velocity is changed to 0 = t = ?
Using first equation of motion:
v = u + at
It will take 27 seconds for a cyclist to stop completely.
