10. At point A, a runner is jogging 5 m/s. Forty seconds later, at point B (Up hill) the jogger's velocity is only 2 m/s. What is the jogger's
acceleration from point A to point B?

Deceleration of 0.075m/s²

Explanation:

Given parameters:

Initial velocity  = 5m/s

Time  = 40s

Final velocity  = 2m/s

Unknown:

The jogger's acceleration  = ?

Solution:

To solve this problem, we use;

         a  =  

a is the acceleration

v is the final velocity

u is the initial velocity

t is the time taken

      a  =   = - 0.075m/s²

answer: b.

explanation:
