1. stephanie schneider is running down the street at 10 m/s. she sees a double-tall latte on
the road ahead of her and starts sprinting. after 5 seconds have passed, stephanie is
running at 15 m/s. assuming she does not change direction, what was stephanie's
acceleration?

Stephanie's acceleration is  1 m/.

Explanation:

In the present case, the initial velocity of the runner is given as 10 m/s. After 5 s, the runner runs with velocity of 15 m/s. If there is no change in direction, then the acceleration can be found easily as the change in velocity per unit time.

So,

Thus, the acceleration will be 1 m/.

So the change in velocity will lead to an acceleration of 1 m/.
