Need help with part (d) and (e)

A soccer ball starts from rest and accelerates with an acceleration of 0.385 m/s? while moving down a 8.50 m long inclined plane. When it reaches the bottom, the ball rolls up another plane, where, after moving 14.75 m, it comes to rest. (a) What is the speed of the ball at the bottom of the first plane (in m/s)? (Round your answer to at least two decimal places.) |-0.22 (b) How long does it take to roll down the first plane (in s)? 6.64 (c) What is the magnitude of the acceleration along the second plane (in m/s?)? 2.55 (d) What is the ball's speed 8.20 m along the second plane (in m/s)? 3.619 You know the initial speed at the bottom of the incline and the acceleration up the incline. You wish to determine the speed of the ball at a specific distance up the incline. You should be able to find a kinematic equation relating the quantities you know to the quantity you wish to determine. m/s (e) What If? You change the angles of the two inclines in such a manner that the new acceleration down the first incline is a, new down = 2a, initial down and up the second incline is a, new up ex initial up, What is the ball's speed 8.20 m up the second plane (in m/s)? 2 11.2859 How can you modify your work from part (a) to determine vh new? How can you modify your work from part (d) to determine v new the new speed up the incline at a specific distance? m/s
