Question

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 at angle β = 30° to the line perpendicular to the inclined
plane. (a) draw a free body

diagram for each block in the system. (b) What is the acceleration
of M1? (c) What is the tension

in the cord? (d) After M2moves 10 cm, what is the velocity of M1?
(The system was initially at

rest)

Answer #1

A block of mass m1 = 3.27 kg on a frictionless plane inclined at

frictionless pulley to a second block of mass m2 = 2.60 kg hanging
vertically (see the figure). (a) What is the acceleration of the
hanging block (choose the positive direction down)? (b) What is the
tension in the cord?

ch4 Q62. A block m1 lying on a frictinless inclined plane is
connected to a mass m2 by a massless cord passing over a pulley. A.
The coefficient of kinetic friction between M1 and the plane is
.15. The two masses are equal to 2.7 kg. As m2 moves down,
determine the magnitude and direction of the acceleration of m1 and
m2 given the angle of inclination is 25 degrees.

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.

A block of mass 1.970 kg is free to slide on a
frictionless, horizontal surface. A cord attached to the block
passes over a pulley whose diameter is 0.150 m , to a
hanging book with mass 3.030 kg . The system is released
from rest, and both the book and the block are observed to move a
distance 1.19 m over a time interval of
0.780 s ; at the instant at which that distance is
measured, the book is still moving downwards and...

A block m1= 0.5kg slides on a plane inclined at 300 to the
horizontal. It is attached to a string which runs over a pulley and
has a mass m2=0.2kg hanging at the other end. The coefficients of

A block with mass m = 14.6 kg slides down an inclined plane of
slope angle 15.8 ° with a constant velocity. It is then projected
up the same plane with an initial speed 4.35 m/s. How far up the
incline will the block move before coming to rest?

In the figure below, m1 = 3.2 kg, m2 = 5.3 kg, and the
coefficient of kinetic friction between the inclined plane and the
