Your driver is taking you to the next meeting and you want to find out certain aspects of the trip while driving around. You start measuring when the car starts the journey as follows.
-A car starts from rest and accelerates uniformly until it reaches 140km/hr. It then continues at this speed for 1 minute and then decelerates to 100km/hr. This deceleration takes place twice as fast as the acceleration. The car then stays at this speed of 100km/hr for some time, and then decelerates again until it comes to rest 1000m later(this distance is from the second deceleration till the car stops). The complete journey takes 6 minutes. 
-a) Which of the following velocity time graphs are the correct shape for this question: A
-         
-        
-b) What is the first acceleration a1 = B
-c) What is the distance s1 = C
-d) What is the distance s2 = D
-e)  What is the distance s3 = E
-f)  What is the distance s4 = F
-g)  What is the distance s5 = G
-h)  What is the time t3 = H
-i)  What is the time t4 = I
-j) What is the time t5 = J
-k) What is the deceleration a2 = K
-l) What is the deceleration a3  = L
-m) What is the total distance the car has traveled in the 6 minutes in km = M
