Problem

A parachutist's speed during a free fall reaches 60 meters per second. What is this speed in feet per second? At this speed, how many feet will the parachutist fall during 20 seconds of free fall? In your computations, assume that 1 meter is equal to 3.3 feet. Do not round your answers. \begin{tabular}{|l|l|} \hline Speed: & $\square \frac{\mathrm{f}}{\mathrm{s}}$ \\ Distance fallen in 20 seconds: $\quad \square \mathrm{t}$ \\ \hline \end{tabular}

Solution

Step 1 :Given that the parachutist's speed during a free fall is 60 meters per second, we need to convert this speed into feet per second. We know that 1 meter is equal to 3.3 feet. So, we can multiply the speed in meters per second by 3.3 to get the speed in feet per second. This gives us \(60 \times 3.3 = 198.0\) feet per second.

Step 2 :Next, we need to calculate the distance the parachutist will fall during 20 seconds of free fall. We can calculate this by multiplying the speed in feet per second by the time in seconds. This gives us \(198.0 \times 20 = 3960.0\) feet.

Step 3 :Final Answer: The speed in feet per second is \(\boxed{198.0}\) and the distance fallen in 20 seconds is \(\boxed{3960.0}\) feet.
