The velocity of a car A relative to a car B is 15.0km/hr in the direction of N30°E. If the velocity of a car B is 30km/hr in the direction N45°W. Determine the actual velocity of car A and it's direction.​

The actual velocity of A is 29.87km/hIt can be obtained by using the cosine rule.From cosine rules,y= √(30² + 15² - 2(30)(15)(cos75°))= √(900 + 225 - 232.94)= √(892.06)= 29.87km/hFor the direction, the sine rule or cosine rule can be usedFrom sine rule,(30)/(sine(Ф+45°))= (29.87)/(sine75°)sin (Ф + 45°) = (30)(sine 75°)/(29.87)= 0.9701Ф + 45° = sin∧-1(0.9701)= 75.95°Ф = 75.95° - 45° = 30.95°As a result, the actual velocity of A is 29.87km/h,N30.95WRead more about Velocity onhttps://brainly.com/question/20359038
