Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

Mission KC6 Average Speed Calculations

The Question

An Olympic sprinter runs the 100-meter dash in 9.50 seconds. Determine the average speed of the runner in m/s. Enter a numerical answer (no units) accurate to the second decimal place.

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

Formula Fix

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

A Very Fine Detail

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.
