Question

which example provides the most complete description of an objects motion?
o the ballerina rotated 10 times in 2 minutes.
o the hiker followed a road heading north for 2 miles in 30 minutes.
o bobby threw a ball 10 meters through the hoop.
o the turtle took 20 minutes to make it to the other side of the road.

Explanation:

To completely describe motion, we need information about distance, direction, and time. The hiker's motion includes a direction (north), a distance (2 miles), and a time - interval (30 minutes). The ballerina's description only has rotational count and time. Bobby's description has distance but no time or direction. The turtle's description has time but no clear distance or direction.

Answer:

The hiker followed a road heading north for 2 miles in 30 minutes.
