is ahead of car.
Answers
Answer:
Explanation:
Relative velocity is given asVab = Va − Vb where Vab is the velocity of a with respect to bHere when the car is speeding at 50 kmph and behind it is a jeep moving at 75 kmph let us say Va = velocity of car and Vb =velocityof jeepthen the velocity of car with respect to jeep in this case will be Vab = Va − Vbthat is Vab = 50− 75 = −25 m/s .It implies that the car appears to move towards it(opposite to its direction of motion) with velocity 25 m/sNow when the jeep is ahead of car then again if we assume Va = velocity of car and Vb =velocity of scooterand velocity of car with respect to jeep to be Vab = Va − Vbthen the velocit of car with respectto scooterwill be again 50 −75 kmph which will be −25 kmph that is this time the car will appear to move away from the jeep at the speed of 25 kmph with respect to scooter
