A skate boarder traveling at a constant speed of 22 m/s on a road comes to a straight incline with a constant slope (do not use g for incline). While going up the incline, the skater has constant deceleration. If she is 16m up the incline after 12.0 s

A) what is the acceleration of the skater as she skates the incline
B) What is the velocity of the skater after 12s?
C) when does the skater reach her highest point on the slope?
