Answer:
The engine of a motorcycle can produce a maximum acceleration of 5m/s^2. Its brakes can produce a maximum retardation of 10m/s^2. What is the minimum time in which it can cover a distance of 1.5 km? So T = 3t/2= 3[20]/2 = 30 secs is the shortest time to complete the journey given the conditions.
