1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....

A mass m = 12 kg is pulled along a horizontal floor with NO
friction for a distance d =6.5 m. Then the mass is pulled up an
incline that makes an angle θ = 25° with the horizontal and has a
coefficient of kinetic friction μk = 0.44. The entire
time the massless rope used to pull the block is pulled parallel to
the incline at an angle of θ = 25° (thus on the incline it is
parallel...

A mass m = 17 kg is pulled along a horizontal floor with NO
friction for a distance d =6 m. Then the mass is pulled up an
incline that makes an angle θ = 37° with the horizontal and has a
coefficient of kinetic friction μk = 0.4. The entire
time the massless rope used to pull the block is pulled parallel to
the incline at an angle of θ = 37° (thus on the incline it is
parallel...

A cart of mass m rolls without friction on a level
surface, and is attached to a light spring of constant k,
the other end of which is attached to a wall. Take the initial
position of the cart, where the spring is neither extended nor
compressed, to be the origin x = 0 of a coordinate system
where positive x values are to the right and positive
vectors point to the right. The cart is pushed to the left...

A block slides from rest, along a track with an elevated left
end, a flat central part, into a relaxed spring, as shown in the
figure. The curved portion of the track is frictionless, as well as
the first portion of the flat part of L = 10 cm. The coefficient of
kinetic friction between the block and the only rough part, D = 10
cm, is given by k = 0.20. Let the initial height of the block be...

SPRING CONSTANT, known as "k", IS 18 N/m
Situation: A 0.80-meter spring is set on top of a table. The tabletop is 1.0 meters in length. The table is pushed up against a wall and one end of the spring is attached to the wall. A woodblock of mass 0.1kg is placed at the other end of the free spring. The woodblock is pushed against the spring causing the spring to compress. When held in...

1. (30 points) A 2-kg block A is pushed up against a spring compressing it a distance r-0.1 m (i.e., the spring is unattached to the block). The block is then released from rest and slides down the 20° incline u it strikes a 1-kg sphere B that is suspended from a 1-m inextensible rope. The spring constant 800 N/m, the coefficient of friction between A and the ground i length of the spring d-1.5, and the coefficient of restitution...

Pendulum Clocks Are Very Important...
1. Pendulum clocks are very important for the history of exploration. Accurate time was the best way to determine one's longitude, since the time of sunrise or sunset depends sensitively on your longitude. In this regard, the great enemy of accuracy was thermal expansion of the pendulum used for the chronometer. We are considering a large mass attached at the end of a brass rod. The mass at the end is much greater than the mass of the rod, so we...
