Question

A baboon is riding his bicycle at 20 m/s. He then stops pedaling and coast to a stop with an average deceleration of 5 m/s2. How far will the baboon travel before he stops?

Answer 1

40 m

Step-by-step explanation:

vf = vo + at f = final o = original

0 = 20 - 5t t = 4 seconds

Average speed = ( 20 - 0 ) / 2 = 10 m/s for 4 seconds = 40 meters

or

df = do + vo t + 1/2 a t^2

= 0 + 20 (4) - 1/2 (5)(4^2) = 40 meters
