8-6. The motion of a particle moving in the horizontal direction as shown in Fig. P8.5 is described by its position x(t). Determine the position, velocity, and acceleration at t = 1.5 s if a. x(t) = 4 cos(5 t) m. b. x(t) = 4 +36 +2 +7t+2 m. c. x(t) 10 sin(10t) +5 est m. = Figure P8.5 A particle moving in the horizontal direction. x(t) v(t) 8-6.
