Physics (AS & A Level) · May / June 2020 · Paper 12 · Question 6

A car X is travelling at a constant speed u along a straight road. At time t = 0 a second car Y is a distance d0 behind car X and travelling at a speed v in the same direction. Speed v is less than speed u. At time t = 0 car Y begins to accelerate with a constant acceleration. Car Y overtakes car X at time t = T. Which graph could best show the variation with time t of the distance d between the cars?
