Final answer:

Given the initial velocity of 0 km/hr, a final velocity of 15 km/hr, and an acceleration of 15 km/hr². The unknown is the distance traveled by Charlie.

Step-by-step explanation:

To determine how far Charlie the moose will travel when accelerating to a certain velocity, we must first identify the givens and the unknowns in the situation below. The givens are the initial velocity (vi) which is 0 km/hr since Charlie starts from rest, the final velocity (vf) which is 15 km/hr, and the acceleration (a) that Charlie experiences, which is 15 km/hr2. Our unknown in this situation is the distance (d) that Charlie travels while accelerating to this final speed. To solve for the distance, we convert the units of velocity to m/s (1 km/hr = 0.27778 m/s), use the kinematic equation d = vit + 0.5at2 with the time (t) being derived from the equation vf = vi + at, and then calculate the value of d.
