Question 22

A car starts from rest and accelerates uniformly to V V\,V m s−1^{-1}−1 in 6 s. It maintains this velocity for 50 s and then decelerates uniformly to rest. The magnitude of the deceleration is 1.5 times the magnitude of the acceleration.

a.

Show that the total journey time is 60 s.

[3]
b.

Sketch a velocity-time graph for the journey.

[3]
c.

Given that the total distance travelled is 1320 m, find VVV.
