In the system shown to the right, M1 = 3 kg and M2 = 6 kg.
Determine the coefficient of static friction that would prevent M1 from sliding.
Thanks!


















Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other by a string that passes through a massless pulley. The stiffness constant of the spring attached to m1 and the wall is k=120N/m and the coefficient of kinetic friction between m1 and the surface is given to be μk=0.2. If the system is released from rest when the spring is at its equilibrium length and m2 is at a...
In the figure below, m1 = 10.0 kg and m2 = 4.5 kg. The
coefficient of static friction between m1 and the horizontal
surface is 0.60 while the coefficient of kinetic friction is
0.30.
(a) If the system is released from rest, what will its
acceleration be?
m/s2
(b) If the system is set in motion with m2
moving downward, what will be the acceleration of the system?

Two masses are arranged as
shown in the picture below with m1 = 5.98 kg and m2 = 2.29 kg. a)
What minimum coefficient of static friction would be necessary to
keep the system stationary? b) When the blocks are released, m2 is
observed to accelerate downward with an acceleration of 1.73 m/s2.
What is the tension in the rope? c) What is the coefficient of
kinetic friction between m1 and the surface? d)

Mass m1 14.9 kg is on a horizontal surface. Mass m2 6.73 kg hangs freely on a rope which is attached to the first mass. The coefficient of static friction between m1 and the horizontal surface is H5 = 0.638, while the coefficient of kinetic friction is μk = 0.144. m1 m2 If the system is set in motion with m1 moving to the right, then what will be the magnitude of the system's acceleration?

Two blocks with masses M1 and M2 are connected by a massless string that passes over a massless pulley as shown. M1 has a mass of 2.25 kg and is on an incline of θ1=43.5° with coefficient of kinetic friction μ1=0.205 . M2 has a mass of 6.15 kg and is on an incline of θ2=35.5° with coefficient of kinetic friction μ2=0.105. The two-block system is in motion with the block of mass M2 sliding down the ramp.Find the magnitude...
Two blocks (M1=5 kg and M2=3 kg) are
stacked on a frictionless surface but there is friction between
them. The coefficient of static friction between the blocks is
μs=0.6 and the coefficient of kinetic friction is
μk=0.3. If a person applies a horizontal force F=60 N to
M1, the blocks move. You do not know if the blocks slip
or accelerate together until you check.

Objects with masses m1 = 8.0 kg and m2 = 5.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. If, when the system starts from rest, m2 falls 1.00 m in 1.70 s, determine the coefficient of kinetic friction between m1 and the table.
Two masses m1 = 5 kg and m2 = 10 kg which are connected by a pulley with mass m2 on an inclined plane of θ= 40. A third block m3 = 8kg is found on block m1. The horizontal surface and inclined surface have no friction, but the coefficient of static friction between the two blocks is 0.3. Will the m3 block stay on block m1 or will it slip? What m2 mass would be needed to cause the...
