Abicyclist is riding to the left with a velocity of 14 m/s . after a steady gust of wind that lasts 3.5 s, the bicyclist is moving to the left with a velocity of 21 m/s
assuming the acceleration is constant, what is the acceleration of the bicyclist?

He accelerated from 14 m/s to 21 m/s in 3.5s so

2 meters per second per second

2 m/s²

Step-by-step explanation:

A bicyclist is riding to the left with a velocity of 14 m/s.

Initial velocity, u = 14 m/s

After a steady gust of wind that lasts, t = 3.5 s

The bicyclist is moving to the left with a velocity of 21 m/s

Final velocity, v = 21 m/s

Hence, The acceleration of the bicyclist is 2 m/s²
