A cyclist moves his cycle from rest with an acceleration of 1m/s squared, for 20 seconds and then he moves with uniform velocity for 1 minute. Finally he applies brakes and stops with a negative acceleration of 2 m/s squared. Determine total distance covered by the cyclist.
The velocity cyclist obtains after 20 seconds is
V = at = 1 [m/s²] * 20 [s] = 20 [m/s].
Time needed to stop the cycle that moves at 20 m/s with deceleration of 2 m/s² is
