REE - Sept. 2001 19. A point travels as described by the following parametric equations x = 10t + 10cos(Tt), y = 10t + 10sin(Trt), z = 10t, where x, y, z are in meters, t in seconds, all angles are in radians. The vector locating the body at anytime is r= ix + jy + kz. Determine the magnitude of the velocity of the body in meters per second at time t = 0.25. A. 33.07 B. 34.57 C. 35.87 D. 33.85
