What is the magnitude of the acceleration of a sprinter running at $10 \mathrm{~m} / \mathrm{s}$ when rounding a turn of radius $25 \mathrm{~m}$ ?
Added by Kelly M.
Step 1
This is the acceleration that keeps an object moving in a circular path. The formula for centripetal acceleration is a = v^2 / r, where: - a is the centripetal acceleration, - v is the velocity of the object (in this case, the speed of the sprinter), and - r is Show more…
