Interpreting date: bob straps on his
in-lineskatesand pushes down a hill. his velocity changes from 0
m/s atthe start to 4.5 m/s exactly 15 s later: what is bob's
averageacceleration?

is Bob's  average acceleration.

Explanation:

Initial velocity of the bob's in-lineskates= u = 0 m/s

Acceleration of the Bob= a  = ?

Final velocity of the bob's in-lineskates= v = 4.5 m/s

Duration of time in which 0 m/s velocity is changed to 4.5 m/s = t = 15 s

Using first equation of motion: v = u + at

is Bob's  average acceleration.

answer: i cant find your answer. do u have another way i can answer it for you : )

explanation:

true is the
