Question

how long will it take for a motorcycle to come to a stop from 35 m/s if it slows down with an acceleration of -12m/s/s?

Answer 1

It would take 3 seconds approximately.

Step-by-step explanation:

since it's going to stop it's final velocity is 0m/s

Now,

acceleration = (v-u)/t

or, a = (0-35)/t

or, -12 = -35/t

or, t = -35/-12

so, t = 2.9 seconds.
