Car A is heading north with a velocity of 14 m/s. Car B is traveling south with a velocity of 19 m/s. What is the relative motion between the two cars?
A. 5 m/s
B. 14 m/s
C. 19 m/s
D. 33 m/s
would this be A, since 19-14 = 5?
Taking the difference is the right approach. However, they are heading in different directions, so the velocities have different signs.
Hope that helps.
thank you!
Yes, you are correct. The relative motion between two objects is calculated by subtracting their velocities. In this case, Car B is traveling south with a velocity of 19 m/s, while Car A is heading north with a velocity of 14 m/s.
To calculate the relative motion, you subtract the velocity of Car A from the velocity of Car B:
Relative motion = Velocity of Car B - Velocity of Car A
Relative motion = 19 m/s - 14 m/s
Relative motion = 5 m/s
So, the correct answer is A. The relative motion between Car A and Car B is 5 m/s.
