(Answered) Starting from rest a runner reaches a speed of 27 ms in 20

Academics

Starting from rest, a runner reaches a speed of 2.7 m/s in 2.0 s. In the same 2.0 s time, a motorcycle increases speed from 38.0 to 43.0 m/s. In both cases, assume the acceleration is constant.

(a) What is the acceleration (magnitude only) of the runner? m/s2

(b) What is the acceleration (magnitude only) of the motorcycle? m/s2
