A car accelerates from rest at S m/s for 5 seconds. It moves with a constant velocity for 15 seconds, and then decelerates at 5 m/s to come to rest in 5 seconds. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion AND determine the total distance the car travelled. (10 pts.) 4.

A bus starts from rest and accelerates uniformly for 20 seconds to a speed of 18 km/h
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!!!
