Car A negotiates a curve of 56-m radius at a constant speed of 54 km/h. When A passes the position shown, car B is 24 m from the intersection and is accelerating south toward the intersection at the rate of 1.9 m/s. Determine the acceleration which A appears to have when observed by an occupant of B at this instant. The x-direction points east and the y-direction points north. N 56 m B 24 m Answer: aA/B = ( i i+ j) m/s2
