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.

1.	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.
