Chapter 4, Problem 51(choose chapter or problem)
Two particles move in the xy-plane. At time t, the positionof particle A is given by x(t)=4t 4 andy(t)=2t k, and the position of particle B is givenby x(t)=3t and y(t) = t2 2t 1.(a) If k = 5, do the particles ever collide? Explain.(b) Find k so that the two particles do collide.(c) At the time that the particles collide in part (b),which particle is moving faster?
