A soccer ball is released from rest at the top of a grassy incline. After 8.6 seconds, the ball travels 87 meters and 1.0 s after this, the ball reaches the bottom of the incline. What was the magnitude of the ball's acceleration, assume it to be constant

The ball's acceleration is 2.35 m/s2

Explanation: Please see the attachment below

The acceleration is  

Explanation:

From the question we are told that

   The distance covered is  

    The time taken is  

    Time taken reach the bottom is  

 According to the equation of motion

since the ball started at rest u =  0 m/s  

     substituting values

=>    

=>      

im guessing the west of station b
