Two particles move in the xy-plane. at time t, the position of particle a is given by x(t)=5t−5 and y(t)=2t−k, and the position of particle b is given by x(t)=4t and y(t)=t2−2t−1.(a) if k=−6, do the particles ever collide? (b) find k so that the two particles are certain to collide. k=(c) at the time the particle collide in (b), which is moving faster? a. particle ab. particle bc. neither particle (they are moving at the same speed)
