Question
m1
A block with mass m, = 8.8 kg is on an incline with an angle 8 = 22° with respect to the horizontal. For the first question
there is no friction, but for the rest of this problem the coefficients of friction are: H, = 0.2 and u, = 0.22.

m,
To keep the mass from accelerating, a spring is attached. What is the minimum spring constant of the spring to keep the
block from sliding if it extends x = 0.13 m from its unstretched length.

4)
m2
Now a new block with mass m, = 16.8 kg is attached to the first block. The new block is made of a different material
and has a greater coefficient of static friction. What minimum value for the coefficient of static friction is needed
between the new block and the plane to keep the system from accelerating?
