Lian 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, Lian is running in 15 m/s. Assuming she does not change direction, what was Lian’s acceleration?

Answer:

Lian'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/.

Hope this will help!
