Question

3. Two blocks of mass m and M = 10.0 ks are connected via a massless and frictionless pully with a configuration as shown. The coefficient of static friction is μs = 0.7 between block and surface, while the coefficient of kinematic fraction is μk = 0.4.

1) Draw free-body diagram for both block (identify all the forces on the two objects

2) What is the maximum mass m for the hanging block so that no sliding occurs?

3) If the mass of the hanging block is m = 9.0 kg, what is the acceleration of the two blocks, and what is the tension in the string?

Answer #1

Two blocks, each of mass m = 6.00 kg , are connected by
a massless rope and start sliding down a slope of incline
θ = 36.0 ∘ at t=0.000 s. The slope's top portion
is a rough surface whose coefficient of kinetic friction is
μk = 0.300. At a distance d = 1.90 m from block
A's initial position the slope becomes frictionless. What
is the velocity of the blocks when block A reaches this
frictional transition point? Assume...

Two blocks are connected by a massless string that runs across a
frictionless pulley with a mass of 5.00 kg and a radius of 10.0 cm.
The first block with an unknown mass of m1 sits on a horizontal
surface and is also connected to a spring with a spring constant of
k = 250 N/m. The coefficient of kinetic friction between the first
block and the surface is 0.400. The second block with a mass of m2
= 6.00...

Two blocks of mass 3.5 kg, and 8.0 kg are connected by a
massless string that passes over a frictionless pulley. The
inclines are frictionless. Find (a) the magnitude of acceleration
of each block and (b) the tension in the string.
answer should be: (2.45m/s2 , 30.6 N) please show me how to get
those answers

Two blocks are attached to opposite ends of a string that passes
over a massless, frictionless pulley (see the figure). Block ? of
mass 10.0 kg lies on a 60.0° incline with a coefficient of friction
of 0.500, and block ? of mass 1.00 kg is attached to a vertical
spring of force constant 200 N/m. The blocks are initially at rest
with the spring at equilibrium. Find the maximum height that the
block ? rises.

string going over a smooth, massless pulley. The table on which the
smaller mass rest is frictionless. The other side of the 2.00 kg
mass is connected to a spring of k=250 N/m and the far end of the
spring is tied to a fixed point. The system is release from rest
with the spring at its relaxed length.
