Kinematic Concepts - Mission KC6 Detailed Help

If a football player runs with an average speed of 9.24 m/s, then how much time (in seconds) would it take to run 94.1 meters? Enter a numerical answer (no units) accurate to the second decimal place.

(Note: Numbers are randomly generated and may differ from those shown here.)

The average speed (vave) of an object can be determined as the ratio of the overall distance traveled (d) per time of travel (t):
ave. speed = distance / time
vave= d / t

This question asks you to determine how much time (t) it will require to fly a stated distance at a stated speed. The equation in the Formula Frenzy section can be used to determine the time. As written, it is set up to solve for average speed. But by multiplying each side of the equation by t and then dividing each side by vave, the variable t will be by itself on the left side of the equation. Substitution of known values of vave and d can be made in order to solve for t.

The Minds On Physics program calculates answers accurate to many decimal places. Your answer does not need to be that precise. The program will allow you to have a 1% deviation from the right answer without being wrong. This means you should enter your answer to at least the second decimal place.
