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 4 seconds. The car maintains this speed for 40 seconds before decelerating to rest. The magnitude of the deceleration is 2 times the magnitude of the acceleration.
show the total time taken for the journey is 46 seconds.
sketch a velocity-time graph for this information.
Given the total distance is 860 m, find the value of VVV.
