Question

A
particle of mass 2kg rest on the surface of a smooth plane inclined
at an angle 30 degrees to the horizontal. It is connected by a
light inelastic string passing over a smooth pulley at the top of
the plane to a particle of mass 5.8kg which is hanging freely.
After the system is released from reat its acceleration ( in m/s)
is?

b) Calculate the force (in N) acting on the pulley due to the
string, if the mass of the particle hanging freely is 10kg.

Answer #1

A block of mass M2 = 8.45 kg on a plane inclined moving down at
angle θ = 50° is
connected by a cord over a massless, frictionless pulley to a
second block of mass M1 = 5.36 kg
on a horizontal surface. The coefficient of kinetic friction
between M1, M2 and the surface is μk
= 0.150, the Force F1 = 11.3 N is acting downward on M1, and the
Force F2 = 21.8 N is acting on
M2...

An object with mass M1M1 of 2.85 kg is held in place on an
inclined plane that makes an angle θθ of 40.0° with the horizontal
(see figure below). The coefficient of static friction between the
plane and the object is 0.566. A second object that has a mass M2M2
of 4.75 kg is connected to the first object with a massless string
over a massless, frictionless pulley.
Calculate the initial acceleration and tension once objects are
released.

incline is 43.0 degrees. The plane is NOT smooth and has a
coefficient of static friction of 0.570 and a coefficient of
kinetic friction of 0.240.
