Questions on Force and Motion (Kinematics)

​An object moves along a smooth inclined plane as shown in the diagram, with an initial velocity of 10 m/s and accelerates at 2 m/s2

 
a).  Calculate the distance the object moved from point A to point B.                       

b). What would be its velocity at point B?                                                                               
c). What would be the average time for the object to move from point A to point B?
