Two builders carry a sheet of drywall up a ramp. The drywall is very thin and is 3.20m long and 2.20m wide. The ramp makes an angle of 18.0 degrees with the horizontal. The lead builder carries a weight of 139.0 N (31.2 lb). What is the weight carried by the builder at the rear if the drywall is carried by the longside (distance = 3.20m between the builders)? What if the drywall is carried by the shorter side (distance = 2.20m between the builders)?
