Particle A is moving with a constant vel...

Particle A is moving with a constant velocity of `V_(A) = 50 ms^(–1)` in positive x direction. It crossed the origin at time `t = 10 s`. Another particle B started at `t = 0` from the origin and moved with a uniform acceleration of `a_(B) = 2 ms^( –2)` in positive x direction.
(a) For how long was A ahead of B during the subsequent journey?
(b) Draw the position (x) time (t) graph for the two particles and mark the interval for which A was ahead of B.
