A box of 350N weight is at rest at the bottom of the plank that is 6.0m long and rises 30 degree above the ground. then the box is pushed up an inclined plank. if the incline is frictionless,and the pushing force is 600 to do the job,what is the work done by the push? what is the velocity of the box at the top of the plank? please show work.
