Question 26

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 18 seconds. The car maintains this speed for 29 seconds before decelerating to rest. The magnitude of the deceleration is 1.5 times the magnitude of the acceleration.

a.

show the total time taken for the journey is 59 seconds.
