A bus starts from rest and accelerates uniformly for 20 seconds to a speed of 18 km/h. It then moves with a uniform velocity and it is finally brought to rest in 100 meteres with a constant retardation. If the total distance travelled is 0.5km. Find the accelration, retartdation and total time taken. My answers are total time = 110s Retardation -1/4ms^-2. Please check if they r correct or not!!!
