Question

If a bicycle has an average acceleration of -0.44 m/s^2, and its initial forward velocity is 8.2 m/s, how long will it take the cyclist to bring the bicycle to a complete stop

Answer 1

Answer:

The value is  $t = 18.6 s$

Explanation:

From the question we are told that

     The average acceleration of the bicycle is $v = -0.44 \ m/s^2$

      The initial forward velocity is  $u = 8.2 \ m/s$

Generally from kinematic equations we have that

      $v = u + at$

Here v is the final velocity of the bicycle and the value is v = 0 m/s

So

      $0 = 8.2 + (-0.44)t$

=>    t = 18.6 s
