Physics 2010 JAMB Past Questions - Question 2: Two cars moving in the same direction have speeds of 100 kmh-¹ and 130 kmh-¹ what is the velocity f the master car as measured by an observer in the slower car ?
Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
C
Explanation
To find the velocity of the faster car as measured by an observer in the slower car, you need to account for the relative velocity between the two cars. The relative velocity is the difference between the velocities of the two cars. In this case, the slower car is the observer.
Relative velocity = Velocity of the faster car - Velocity of the slower car
Relative velocity = 130 km/h - 100 km/h
Relative velocity = 30 km/h
So, the velocity of the faster car as measured by an observer in the slower car is 30 km/h in the same direction as the motion of the slower car.
