A particle X travels with a constant velocity of along a straight line. It passes a particle Y which is stationarity. One second later particle Y accelerates at . How long after being passed it take for particle Y to draw level with the particle X? Leave your answer in surd form.
for particle 'x' ,
t= T seconds.
and for particle 'y' , and t= T-1 seconds
I am pretty sure you use this formula
but I am not sure how to put all this info together and make one equation any help ?
