A cyclist starts from rest, accelerates uniformly for 4.0 s, then rides at constant speed, and finally decelerates uniformly to rest over a distance of 25 m. The total time from start to stop is 20.0 s and the total distance travelled is 300 m. Determine (a) the magnitude of the acceleration during the first phase and (b) the magnitude of the deceleration in the final phase. Give your answers to two significant figures.

Answer Options

A. a ≈ 3.2 m/s², deceleration ≈ 5.8 m/s²
Correct Answer B. a ≈ 4.5 m/s², deceleration ≈ 6.5 m/s²
C. a ≈ 4.5 m/s², deceleration ≈ 5.0 m/s²
D. a ≈ 5.0 m/s², deceleration ≈ 7.2 m/s²
Correct Answer
B
Correct Option:
a ≈ 4.5 m/s², deceleration ≈ 6.5 m/s²
