How long does it a take a runner, starting from rest to reach max speed, 30 f/s given acceleration 8 f/s^2? after finding the time, calculate the distance traveled in that time.

Explanation:

Given that,

Initial sped of the runner, u = 0

Final speed of the runner, v = 30 ft/s

Acceleration of the runner,

Let t is the time taken by the runner. It can be calculated using first equation of motion as :

t = 3.75 seconds

Let s is the distance covered by the runner. Using the second equation of motion as :

s = 56.25 feet

Hence, this is the required solution.

it doesn't. it was imagined up in the middle ages.
