Question

if a bicyclist starts from a resting position and reaches a speed of 10 meters per second in 40 seconds, what was his acceleration during this time? assume he accelerated in a constant way.

Answer 1

Acceleration (magnitude) = (change in speed) / (time for the change)

= (10 m/s - 0 m/s) / (40 sec)

= (10/40) m/s²

= 0.25 m/s²
