A block (425‐kg) is sitting on a ramp, which is angled 25.0‐degrees above the horizontal. A rope pulls up the ramp with 275N and another rope pulls horizontally at 175N. The coefficient of static friction is 0.855. The coefficient of kinetic friction is 0.655.
a. Draw a free‐body diagram for this case. Make sure to indicate a coordinate system.
b. Write out Newton’s 2nd Laws, once for each dimension.
c .Determine the acceleration of the block.
d. Pick one force from your free‐body diagram. Describe its paired force according to Newton’s 3rd Law. (Which object it is acting on, its direction, and its amount.)
