A car starts from rest and accelerates at a constant rate to the speed of V m s−1V\text{ m s}^{-1}V m s−1 in 12 seconds. The car maintains this speed for 38 seconds before decelerating to rest. The magnitude of the deceleration is 1.5 times the magnitude of the acceleration.
show the total time taken for the journey is 58 seconds.
sketch a velocity-time graph for this information.
Given the total distance is 1440 m, find the value of VVV.
