Question

1. bus a is traveling north at 90km/hr. bus b is traveling south at 90km/hr. which statement is true about the velocity of the buses? (2 pts)

a. their velocities are the same.
b. the velocity of bus a is less than the velocity of bus b.
c. the velocity of bus a is greater than the velocity of bus b.
d. their velocities are different because their directions are different.

Explanation:

Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. Bus A travels north at 90 km/h, and Bus B travels south at 90 km/h. Their speeds (magnitudes) are equal, but their directions are opposite. So, their velocities are different because velocity depends on direction. Option a is wrong as directions differ. Options b and c are wrong as speeds (magnitude of velocity) are equal. Option d correctly states velocities differ due to different directions.

Answer:

d. Their velocities are different because their directions are different.
