Question

1. Stephanie Schneider is running down the street at 10 m/s. She sees a double-tall latte on

Answer 1

Stephanie's acceleration is  1 m/$s^{2}$.

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, $Acceleration = \frac{Change in velocity}{Time}=\frac{(Final velocity -Initial velocity)}{Time}$

$Acceleration = \frac{15-10}{5}=\frac{5}{5}=1 m/s^{2}$

Thus, the acceleration will be 1 m/$s^{2}$.

So the change in velocity will lead to an acceleration of 1 m/$s^{2}$.

Answer 2

Answer:15m/s-10m/s over 5s

Explanation:its a fraction the 15m/s and 10m/s are over the 5s
