Two blocks A and B start with slide across a table. The figure below shows a bird’s eye view:
The mass of Block A is m. The mass of Block B is 2m. Each block starts with identical momentum p?. Each block slides across a table with a coefficient of sliding friction ?. Each block decelerates due to sliding friction and then comes to rest before reaching the edge of the table.
a) Which block comes to rest first? Block A, Block B, or is it a
tie? Explain your answer.
b) Which block slides the greater distance? Block A, Block B, or is
it a tie? Explain your
answer.
c) Draw a free body diagram indicating all forces on the table. What is the net force on the table? Hint: don’t plug and chug. Think!
d) In term of p, m and ?, how much work is done by the table on each of the two blocks? e) Is mechanical energy conserved in this problem? If not, where did the energy go?

I need help on part G!!!!! Blocks A and B are on a frictionless horizontal surface. Block A is to the left of block B. Both blocks are initially at rest. Block A has a mass of 2.1 kg and B has a mass of 1.5 kg. Block A is struck from the left with a hammer. The average force of this impact is 210 N and lasts for 0.09 seconds. Block A slides to the right, strikes and sticks...

In the figure, a stationary block explodes into two pieces L and
R that slide across a frictionless floor and then into regions with
friction, where they stop. Piece L, with a mass of 2.0 kg,
encounters a coefficient of kinetic friction ?L = 0.40 and slides
to a stop in distance dL = 0.15 m. Piece R encounters a coefficient
of kinetic friction ?R = 0.50 and slides to a stop in distance dR =
0.22 m. What was...

A track consists of a frictionless arc XY, which is a
quarter-circle of radius R, and a rough horizontal section YZ, as
shown above.
In trial 1, Block A of mass M is released from rest at point
X, slides down the curved section of the track, and collides
instantaneously and inelastically with block B, with mass M, at
point Y. The two blocks move together to the right, sliding past
point P, which is a distance L from point...

As shown below (not to scale), a block of mass starts from rest
and slides down a frictionless ramp of height h. Upon reaching the
bottom of the ramp, it continues to slide across a flat
frictionless surface. It then crosses a "rough patch" on the
surface of length d=10m. This rough patch has a coefficient of
kinetic friction uK=.1. After crossing the rough patch, the block's
final speed is vf=2m/s. What is the height of the ramp? Hint: I...

A 2.00-kg block lies at rest on a frictionless table. A spring, with a spring constant of 100 N/m, is attached to the wall and to the block. The second block of 0.50 kg is placed on top of the first one. The 2.00-kg block is gently pulled to a position x = + A and released from rest. There is a coefficient of friction of 0.45 between the two blocks. (a) Assuming that the top block does not slide,...
