A car starts from rest and accelerates at a constant rate to the speed of Vms−1V\text{ms}^{-1}Vms−1 in 4 seconds. The car maintains this speed for 30 seconds before decelerating to rest. The magnitude of the deceleration is 2 times this magnitude of the acceleration.
Show the total time taken for the journey is 36 seconds.
Sketch a velocity-time graph for this information.
Given the total distance is 1320m, find the value of VVV.
