i think this is an easy question but i forgot how and the book doesn't want to tell me. can anyone tell me how to figure this out? thanks. A soccer ball is released from the top of a smooth incline. After 4.58 s the ball travels 10.8 m. One second later it has reached the bottom of the incline. (question 1)Assume the ball's acceleration is constant and determine its value ( m/s2). (question 2)How long is the incline?
