How long does it take for a cyclist to travel 30m, starting with an acceleration of 0.75m / s2.
| February 1, 2021 | education
These tasks: S (distance that the cyclist must travel) = 30 m; a (the acceleration with which the cyclist began to move) = 0.75 m / s2.
The duration of a cyclist’s movement can be expressed from the formula (we consider movement without an initial speed): S = a * t ^ 2/2 and t = √ (2S / a).
Calculation: t = √ (2 * 30 / 0.75) = √80 = 8.94 s.
Answer: It takes a cyclist 8.94 seconds to travel 30 m.
