Question

Blocks of mass m_{1} and m_{2} slide on a track
that consists of two curved, frictionless sections connected by a
straight, horizontal surface of length L. The mass of block 2 is
1.5 times the mass of block 1, that is, m_{2}=
1.50m_{1}. The coefficient of kinetic friction between the
blocks and the horizontal surface is 0.32. Block m_{1} is
released from rest at height H= 5.00L above the horizontal surface
and sticks to block m_{2} when they collide. Determine the
value of x at the position at which the blocks come to rest.

Answer #1

Two blocks of masses m1 = 1.95 kg and m2 = 3.90 kg are each
released from rest at a height of h = 6.00 m on a frictionless
track, as shown in the figure below, and undergo an elastic head-on
collision. (Let the positive direction point to the right. Indicate
the direction with the sign of your answer.) Two blocks are on a
curved ramp similar in shape to a half-pipe. There is a flat
horizontal surface with opposite...

Two blocks of mass m1 = 9.20 kg and m2 are connected by a light
string. When a horizontal force F = 105 N is applied to m1 as shown
in the figure below, the acceleration of the system is 3.20 m/s2
towards the left and the tension in the string connecting the two
blocks is 62.0 N. The blocks are moving on a rough surface with an
unknown coefficient of kinetic friction. Determine the coefficient
of kinetic friction between...

Two blocks with masses m1 = 1.10 kg and m2 = 3.50 kg are
connected by a massless string. They are released from rest. The
coefficent of kinetic friction between the upper block and the
surface is 0.440. Assume that the pulley has a negligible mass and
is frictionless, and calculate the speed of the blocks after they
have moved a distance 68.0 cm.

A block with a mass m1=2.3kg is sliding along a frictionless
surface with a velocity of 7.3m/s. It collides inelastically with
mass m2=1.7kg and the two blocks stick together. They then slide
down a frictionless incline with a Height 95cm. How fast are they
going when they reach the bottom of the incline?

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

Objects with masses m1 = 12.0 kg and
m2 = 8.0 kg are connected by a light string

when the system starts from rest, m2 falls 1.00
m in 1.48 s, determine the coefficient of kinetic friction between
m1 and the table.
Express the friction force in terms of the coefficient of kinetic

masses and the...

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

the speed of the block with mass m2 after it travels

Two blocks of masses m1 = 2.00 kg and m2 =
4.00 kg are released from rest at a height of h = 5.00 m on a
frictionless track as shown to the right. When they meet on the
level portion of the track, they undergo a head-on, elastic
collision. Determine the maximum heights to which m1 and
m2 rise on the curved portion of the track after the
collision.

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=46.5∘ with
coefficient of kinetic friction μ1=0.205.
M2 has a mass of 6.05 kg and is on an incline of θ2=33.5∘ with
coefficient of kinetic friction μ2=0.105.

sliding down the ramp.
