Question

In the figure, two blocks are shown with an inclined plane. The
two blocks are connected by a massless string strung over a
massless pulley. The mass of Block *#1* is 3.57 kg and that
of Block *#2* is 11.0 kg. The angle *θ* of the
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.

Taking the positive direction to be up the incline, determine the
following:

(a) the acceleration of Block *#1* if it is initially at
rest.

m/s^{2}

(b) the acceleration of Block *#1* if it is already moving
up the plane.

m/s^{2}

(c) the acceleration of Block *#1* if it is already moving
down the plane.

m/s^{2}

Two blocks (m1=5.5kg, m2=7.2kg
) are connected by a string that passes through a massless pulley
as shown in the Figure. The first block with mass
m1 slides up the inclined
plane when the system is released. The inclined plane makes an
angle θ = 310 with the
horizontal and the kinetic friction coefficient between the
inclined plane and m1 is
=0.35. Take g=10m/s2 Find
the speed of the block with mass m2 after it travels
h=5.6m.

Two blocks are connected by a string that passes over a
massless, frictionless pulley, as shown in the figure. Block A,
with a mass mA = 2.00 kg, rests on a ramp
measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs
vertically below the pulley. Note that you can solve this exercise
entirely using forces and the constant-acceleration equations, but
see if you can apply energy ideas instead. Use g = 10
m/s2. When the system is released...

In the figure, a 5.40 kg block is sent sliding up a plane
inclined at θ = 37.0° while a horizontal force
