    Carrying Drywall
    Two builders carry a sheet of drywall up a ramp.

    Assume that W = 2.00 m, L = 3.20 m, θ = 25.0°, and that the lead builder carries a (vertical) weight of 155.0 N (34.8 lb). What is the (vertical) weight carried by the builder at the rear?

    What is the weight (in N) he must now carry?
