Oh come now guy? How hard is the object being pushed? How much mass does the object have? How much friction is the slope providing? How much gravity is the object under? It gave you all those numbers i assume. With those you can determine if the object can be pushed up the slope and exactly how fast. (Force of push must exceed the tendancy to fall back of the object + friction provided by the slope. If it does you can determine how fast up the slope the object can be pushed pending the ratio of force applied to object vs friction plus mass& gravity resistance.)
