At
a particular instant, two cars A and B are traveling at 20 km/hr and 40
km/hr. Car B is decreasing its speed by 1600 km/hr^{2} while A is
decreasing its speed at 1000 km/hr^{2}. A ball thrown by a person
in A is caught by a person in car B. Determine the velocity of the ball.
Also find the acceleration of B with respect to A, if B moves along a curve
having radius of curvature as 2 kms. 1) 29.46 km/hr & 2748.8 km/hr^{2} 2) 22.34 km/hr & 4567.4 km/hr^{2} 3) 32.78 km/hr & 1234.3 km/hr^{2} 4) 87.45 km/hr & 1245.6 km/hr^{2}. 

The fixed axes x,y
are established at a point on the ground,while translating x',y' axes
are attached to car A.
