m. Figure 1 In the diagram above: The string connecting m and m2 is massless and stretchless; the pulley is massless and frictionless; m1 is on a horizontal surface; and m2 is hanging from the connecting string.
Two blocks are connected by a massless, stretchless string. One of the blocks is at rest, and remains at rest, on a
horizontal surface. The string goes over a massless, frictionless pulley. The second mass simply hangs from the string.
Between the first block and the pulley the string is parallel to the horizontal surface.
a) Draw the free-body diagram for the first block (the one on the surface).
b) Draw the free-body diagram for the second block (the hanging mass).
c) Setup Newton’s second law for the first block.
d) Setup Newton’s second law for the second block.
e) Symbolically, what is the magnitude of the tension in the string?
f) Symbolically, what is the magnitude of the static frictional force that acts on the first block?
Answer the following questions using the equations you derived in parts (e) and (f) above.
g) What is the magnitude of the tension if m1 is 5.00 kg and m2 is 1.00 kg?
h) What is the magnitude of the static frictional force if m1 is 5.00 kg and m2 is 1.00 kg?
i) What is the magnitude of the tension if m1 is 2.00 kg and m2 is 1.00 kg?
j) What is the magnitude of the static frictional force if m1 is 2.00 kg and m2 is 1.00 kg?
k) What is the magnitude of the tension if m1 is 5.00 kg and m2 is 2.00 kg?
l) What is the magnitude of the static frictional force if m1 is 5.00 kg and m2 is 2.00 kg?
m) What is the magnitude of the tension if m1 is 5.00 kg and m2 is zero?
n) What is the magnitude of the static frictional force if m1 is 5.00 kg and m2 is zero?
