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

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!
