I'm not sure how to solve this problem

2. Two particles move along the x-axis. For 0 s t s 8, the position of particle P at time t is given by Xp (t) = In(t - 2t+ 10), while the velocity of particle Q at time t is given by vo(t) = t - 8t + 15 . Particle Q is at position x = 5 at time t = 0. (a) For O s t s 8, when is particle P moving to the left? (b) For O s t s 8, find all times t during which the two particles travel in the same direction. (c) Find the acceleration of the particle Q at time t = 2. Is the speed of particle Q increasing, decreasing, or neither at time t = 3? Explain your reasoning
