the kinetic energy of an olympic bobsled team over a course is graphed. the shape of the curve is parabolic (u - shaped). what dependent variable and unit is illustrated by the graph?\na mass (kg)\nb time (seconds)\nc velocity (m/s)\nd acceleration (m/s²)

Answer

Explanation:

Step1: Recall kinetic energy formula

Kinetic energy $K = \frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity. Mass is a constant for the bobsled team, and kinetic - energy changes with velocity.

Step2: Analyze the graph

The graph shows the kinetic energy of the bobsled team over a course. Kinetic energy depends on velocity. As velocity changes, kinetic energy changes. Time is usually the independent variable in such motion - related graphs, and kinetic energy (which depends on velocity) is the dependent variable among the given options.

Answer:

C. velocity (m/s)
