You have been hired to develop a package transfer slide for a global company. The slide has length L. The slide is to be able to handle uniform boxes of mass m, height H, square widths W. If the slide is to be of slope tan , determine the restrictions on the dimensions of the boxes, the length and angle of the slide, the friction, etc in order to use the slide. Assume the slide has friction (s; k). Assume the boxes enter the slide smoothly with speed Vo parallel to the slide. The boxes cannot stop or tip while on the slide. Use the six step process.
