A.P. Calculus – Additional Homework for Motion You may use your calculator 1. A particle is moving along the x -axis with velocity, ( 29 sin 2 v t t = , 0 t v . At time 2 t π = it has position x = 3. Find the total distance, s traveled by this particle on the interval 0 t . 2. A particle is moving along the x -axis so that at time t its acceleration is ( 29 cos a t t = . At time t = ½, the velocity, v of the particle is ½. a) Find the velocity of the particle at any time t . b) Find the minimum velocity of the particle. c) Find the equation for the position x ( t ) if x (0) = 0. d) What is the first time t > 0 that the particle returns to the origin? 3. A particle is moving with velocity: 2 ( ) 9 18 = - + v t t t with distance, s measured in meters, left or right of zero, and t
