A 1.1 kg book is lying on a 0.77 m -high table. You pick it up and place it on a bookshelf 2.3 m above the floor.
1. How much work does gravity do on the book?
2. How much work does your hand do on the book?

How do you find work?

work done is equal to the change of graviational potential energy here: mgh

In general, work is force*distance*cosineAnglebetween force and distance.
