a particle travels on the x-axis so its velocity at time t is given b v(t) = 1/2 - sint for 0 less than or equal to t less than or equal to 2pi. For what values of t is the particle moving to the right? If the particle starts at x = 3, what is the final position of the particle? What is the total distance traveled by the particle? When t = pi/4, is the speed of the particle increasing or decreasing? Justify
