Question

Michael is biking on a trail and is accelerating at a rate of 1.2 m/s/s for 15 seconds. He began this part of his ride with a velocity of 1.62 m/s. Determine Michael's final velocity?

Answer 1

Answer:

Michael's final velocity is 19.62 m/s.    

Explanation:            

We can find the final velocity of Michael by using the following kinematic equation:

$v_{f} = v_{0} + at$   (1)    

Where:

$v_{f}$: is the final velocity =?

$v_{0}$: is the initial velocity = 1.62 m/s

a: is the acceleration = 1.2 m/s²

t: is the time = 15 s

By entering the above values into equation (1) we have:

$v_{f} = 1.62 m/s + 1.2 m/s^{2}*15 s$

$v_{f} = 19.62 m/s$

Therefore, Michael's final velocity is 19.62 m/s.

I hope it helps you!
