A car starts from rest and accelerates at a constant rate to the speed of Vms−1V\text{ms}^{-1}Vms−1 in 6 seconds. The car maintains this speed for 50 seconds before decelerating to rest. The magnitude of the deceleration is 1.5 times this magnitude of the acceleration.
Show the total time taken for the journey is 60 seconds.
Sketch a velocity-time graph for this information.
Given the total distance is kmk\text{m}km, find the value of V V\,V in terms of kkk.
