A particle, P, is moving along the x-axis. The velocity of particle P at time t is given by vP?(t)=sin(t1.5) for 0?t??. At time t=0, particle P is at position x=5. A second particle, Q, also moves along the x-axis. The velocity of particle Q at time t is given by vQ?(t)=(t?1.8)?1.25t for 0?t??. At time t=0, particle Q is at position x=10. (a) Find the positions of particles P and Q at time t=1. (b) Are particles P and Q moving toward each other or away from each other at time t=1 ? Explain your reasoning. (c) Find the acceleration of particle Q at time t=1. Is the speed of particle Q increasing or decreasing at time t=1 ? Explain your reasoning. (d) Find the total distance traveled by particle P over the time interval 0?t??. Write your responses to this question only on the designated pages in the separate Free Response booklet.
