The car A has a forward speed of 16 km/h and is accelerating at 3.1 m/s2. Determine the velocity and acceleration of the car relative to observer B, who rides in a nonrotating chair on the Ferris wheel. The angular rate Ω = 3.4 rev/min of the Ferris wheel is constant. Answers: vA/B = ( i + j) m/s aA/B = ( i + j) m/s2
