work power energy, Physics

Assignment Help:
A block of mass 2 kg is pulled up on a smooth incline making angle 30 degrees with horizontal . if block moves with an acceleration of 1 m/s2 , find
a) Power delivered by the pulling force at a time 4 sec after motion starts
b)average power deliverd after 4 sec the motion starts
***MY DOUBT
I am very weak in kinematics , so plz explain that the formula s=ut+1/2at^2 gives displament or distance. and if it gives displacement then it will only give the length of base of the incline and not d length of hypotenuse which if needed?
