mr. smith is designing a race where velocity will be measured. which course would allow velocity to accurately get a winner?\n a 5 mile course from the center of town heading north to the outskirts of town\n a 100 meter swim in a 50 meter pool\n a 2 mile run around a 400 meter track\n a 10 mile bike course that zigzags through the mountains and back again

Answer

Brief Explanations:

Velocity is a vector quantity that requires both magnitude and direction. A 5 - mile course from the center of town heading north has a definite direction and magnitude can be measured as distance over time. In a 100 - meter swim in a 50 - meter pool, the swimmer goes back and forth, changing direction. A 2 - mile run around a 400 - meter track and a 10 - mile bike course that zigzags through the mountains and back again also involve multiple direction changes. So, the first option is best for measuring velocity as it has a single, unchanging direction.

Answer:

a 5 mile course from the center of town heading north to the outskirts of town
