A passenger in the automobile B observes the motion of the train car < i="">. At the instant shown, the train has a speed of 18 m/s and is reducing its speed at a rate of 1.5 m/s2. The automobile is accelerating at 2 m/s2 and has a speed of 25 m/s. Determine the velocity and acceleration of A with respect to B. The train is moving along a curve of radius < i=""> = 300 m.<><>

A. vA/B = (25.0i+18.00j) m/s, aA/B = (2.00i-1.500j) m/s2
B. vA/B = (25.0i+18.00j) m/s, aA/B = (0.920i-1.500j) m/s2
C. vA/B = (-25.0i-18.00j) m/s, aA/B = (-2.00i+1.500j) m/s2
D. vA/B = (-25.0i-18.00j) m/s, aA/B = (-0.920i+1.500j) m/s2
