A block is pushed out a constant speed up a ramp from point a to point B. the hand exerts a force on a block that is parallel, keep in mind that there is friction between the block and the ramp and the distance between points a and b is 1 m

With the information provided above the work done by hand as the block travels from point a to point B is which of the following?

1. zero
2. greater than 1 m times the force applied by the hand
3. none of above
4. Equal to one meeting time is the
equal to 1 m time is the force applied by the hand
5. less than 1 million times before I supplied by the load but not zero
