You exert a 44 N push on an object (90 kg) parallel to a ramp, and the ramp is inclined at an angle of 33 degrees above the flat floor. What is the work done by your push, and the work done by the normal force from the floor on the object as it moves 17 m along the ramp?

(a)Wpush=Wpush= 627 J, WN=WN= 0 J
 (b)Wpush=Wpush= 627 J, WN=WN= 1.26×104 J
 (c)Wpush=Wpush= 748 J, WN=WN= 1.26×104 J
 (d)Wpush=Wpush= 748 J, WN=WN= 0 J
