1.Car A rounds a curve of 129-m radius at a constant speed of 42 km/h. At the instant represented, car B is moving at 83 km/h but is slowing down at the rate of 4.9 m/s2. Determine the velocity and acceleration of car A as observed from car B.
vA/B =( _ i + _j) m/s
aA/B =( _i + _j) m/s2
2.The jet transport B is flying north with a velocity vB = 505 km/h when a smaller aircraft A passes underneath the transport headed in the 68° direction shown. To passengers in B, however, A appears to be flying sideways and moving east. Determine the magnitudes of the actual velocity of A and the velocity which A appears to have relative to B.
Aircraft A is going in northeast direction
vA = _ km/h
vA/B = _ km/h
