A cyclist acceleration from 0m/s to 8m/s in 3second. what is his acceleration?

2.66 m/s² .

Explanation:

Initial velocity , u = 0 m/s

Final Velocity , v = 8 m/s

Time Taken , t = 3 s

So , Acceleration = (v-u)/t = (8 m/s - 0 m/s) /3 sec . = 8/3 m/s² = 2.66 m/s²

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
