Answer the attached question and its sub-parts. Thanks

2. Before recent automotive design changes, it was not unusual to have to lean
forward and extend the arms while placing an object into the trunk of a car. Assume
the driver lifts a 60-lb box from the ground into a trunk. Being lazy, the driver simply
twists 90° to pick up the box from the certain level (V=40) at a short horizontal
distance (H=1Oin). The vertical travel distance is the difference between the vertical
location of the box at the destination (assume the bottom of the trunk is 34in from the
ground) and the vertical location of the box at the destination (V=6), yielding D=34.
Assume that this is a one-shot lift; therefore FM=1. Also assume that the box is fairly
small and compact, but has no handles. Thus, coupling is fair with CM= .35. Assume
a longer reach (H=12in) into the trunk because of the bumper and high trunk lip and
no twisting for the destination.
a.) Determine the RWL of the origin.
b.) From question "A", determine the RWL of the destination.
c.) From question "B", determine the Lifting Index of the worker.
