Question and answer
Q: When running, the head should be pointed at the runner's feet.
A: Magnitude of average acceleration = (change of speed) divided by (time for the change) Average 'A' = (6 - 4) / 20 = 2/20 = 0.1 meter per second2 - That's the average over the 20 seconds. [ [ We don't know anything about the value of the acceleration at any particular instant during the 20 seconds. - We're working entirely with scalars ... speed, not velocity, and magnitude of
acceleration ... since we don't know anything about the runner's direction at any time during the whole event. ] ]

User: Is it true or false that when running, the head should be pointed at the runner's feet.

Weegy: False. Your head should be focused on the ground about 10 to 20 feet ahead of you. Don't stare at your feet. Not only is this proper running form, but it's also a safer way to run because you can see what's coming and avoid falling.
