Acceleration: How long will it take a cyclist

Biology
1 answer:
melisa1 [442]2 years ago
8 0

Answer:

It will take 27 seconds for a cyclist to stop completely.

Explanation:

Initial velocity of the cyclist= u = 13.5 m/s

Acceleration of the driver = a  = -0.50 m/s^2

Final velocity of the cyclist = v = 0

Duration of time in which 13.5 m/s velocity is changed to 0 = t = ?

Using first equation of motion:

v = u + at

0 =13.5 m/s+(-0.50 m/s^2)\times (t)

-13.5 m/s=-0.50 m/s^2\times t

t=\frac{-13.5 m/s}{-0.50 m/s^2}=27 s

It will take 27 seconds for a cyclist to stop completely.
