\Hy‘ 0* C‘s—(1)005 Discussion # Full Name: Q2. You have taken a summerjob at a warehouse and have designed a method to help get heavy packages up
a 15° ramp. In your system a package is attached to a rope which runs parallel to the ramp and over a pulley at,
the top of the ramp. After passing over the pulley the other end of the rope is attached to a counterweight
which hangs straight down. In your design the mass of the counterweight is always adjusted to be twice the
mass of the package. Your boss is worried about this pulley system. In particular, she is concerned that the
package will be too difficult to handle at the top of the ramp and tells you to calculate its acceleration. To
determine the influence of friction between the ramp and the package you run some tests. You find that you
can push a 50 kg package with a horizontal force of 250 N at a constant speed along a level floor made of the
same material as the ramp. (Hint: Work out the question symbolically and plug in the numbers at the end.) T, a : “M20“

which m2 does not slip either up or down along the wedge. All surfaces
are frictionless. Represent your answers in the simplest possible form in
